Assassin
Avon and the others discover that they are being hunted by a top notch killer whose services have been paid for by Servalan. Avon and Tarrant fight the odds and sometimes each other to survive, but in the end, it turns out that Avon, underestimating the opposite sex, has been fooled by Servalan and a brilliant female killer – and it is Soolin who saves him.

Busted out of the ranks of the Federation Space Command after his trial, Travis is on the run and out for revenge – on all of humanity, if necessary. He makes contact with an alien force from beyond Earth’s galaxy and offers to join them in an attempt to enter and conquer Federation space. To make that possible, however, Travis must track down a neurosurgeon named Docholli, the only man who is said to know where the Federation’s top secret central control is. During his attempts to track down Docholli, Travis runs afoul of a pair of bounty hunters out to collect the Federation’s price on his head. Only one of them, Kane, survives the ensuing firefight, and he promises to get his revenge on Travis, no matter how long it takes. Some years later, Kane joins another bounty hunter, who he doesn’t realize is former freedom fighter Roj Blake, on the lawless planet of Gauda Prime. Blake is looking for Lafayette, a pirate whose attack on an arms shipment resulted in the death of former Liberator crew member Jenna Stannis. Kane, however, is still hoping to catch up with Travis. And when he learns who Blake is, and that Blake got to Travis before he did, Kane will leave an indelible mark of his own.
Seven years after the massacre of his crewmates and the death of Blake on Gauda Prime, Kerr Avon comes out of seclusion to hear a proposition from an anti-Federation rebel named Lydon on a distant, unnamed world. Lydon has contacted Elise, Avon’s sometime-lover, to try to get Avon involved in an attempt to raid a shipment of Federation gold. Avon is skeptical of how Lydon hopes to help the resistance movement with what is essentially an interplanetary train robbery, and upon hearing Lydon’s plan he’s even more incredulous. But Avon still has an ace up his sleeve – he consults Orac to help him devise a more cohesive plan of action. Before any of those plans can be put into practice, Federation troops converge on Avon, Elise and the others, mounting a strike so precise that they must be getting information from Elise, her strong-arm cohort Kelso, or Lydon. Again, Avon comes to believe that the person he wanted to trust most has betrayed him, and he kills Elise. But this time, his actions and even his contingency plans have been anticipated by Federation psychostrategists, and Avon is captured and brought to Servalan, who has reclaimed her seat of power. But as part of her strategy to remain in power, Servalan has decided she needs enemies to keep the Federation distracted, and she intends for Avon to keep the resistance movement alive…even if it means that the man Avon is now will cease to exist. 
An unusually vivid nightmare gives Avon a horrifying preview of Servalan’s latest scheme. Using a jewel of alien origin, she can inflict her will upon others in a very limited fashion. A sudden escape from a Federation interceptor leaves Scorpio’s newly-installed stardrive drained. Since the stardrive’s advanced power cells can only be procured from a Federation installation, Avon decides to strike Servalan’s current hiding place, the planet Feron, where she is researching the origins and potential power of her new weapon. Avon and Vila eavesdrop in hiding as a scientist reveals the crystal’s secrets (and then condemns himself to a premature death by admitting that he knows that Servalan isn’t “Commissioner Sleer”). From that moment, the race is on to find a jeweled diadem whose telekinetic and telepathic properties would give its wearer more than enough power to topple the Federation. But when Avon learns that an even more powerful crown, of which the diadem is only a part, could give him the ability to rule the entire galaxy… why stop with just the Federation?
Avon hatches a risky plan to take over the planet Syndexia, the last remaining source of the hyperdrive fuel substance called Syndeton. But the already delicate plot is unraveled when Vila gets drunk in a bar on another planet and mentions Syndexia as the crew’s next destination. Vila is only barely rescued by the others as a Federation squadron moves in. Thanks to Vila’s carelessness, Servalan is alerted to Avon’s next destination, yet he presses on. Avon’s concern with Syndexia is not just with the coup to be gained by taking over the supply of Syndeton, either – in so doing, he intends to overthrow Madame Gaskia, Syndexia’s ruler, who once betrayed Avon to the Federation long before he joined Blake. Servalan is interested not only in the power to be harvested from Syndeton, but from its potential as a mind-controlling substance as well, an ability she tests by taking over Tarrant. Before long, the chase is on to find Dr. Rossum, a missing Federation scientist whose research into Syndeton could unlock its dangerous mind-control abilities. Scorpio’s crew finds Rossum first, but at the last minute, Avon insists on conceding this battle to Servalan – and the spoils could be control over every life form in the galaxy.
In the distant future, the tyrannical Federation decides to do away with its most persistent opponent: freedom fighter Roj Blake. Blake is sentenced to exile on the prison colony planet Cygnus Alpha after a conveniently quick trial convicts him on false charges that he molested several children. Aboard the prison ship London en route to Cygnus Alpha, Blake meets fellow prisoners Jenna Stannis, a hard-bitten smuggler, and cynical computer expert Kerr Avon. When they’re enlisted as skilled cannon fodder for a mission to salvage an enormous alien spacecraft, the three prisoners take the opportunity to make an escape attempt. The Federation officer overseeing the prisoners, Mezen, is trapped aboard the alien ship with them. Blake decides to recruit more crew memebrs from the remaining prisoners ferried to Cygnus Alpha by the London, but he finds them under a different iron fist there, as prisoners already living there have set up their own strict society, ruling by the fear of God. Only two of the prisoners, master thief Vila Restal and convicted killer Oleg Gan, opt to join Blake’s crew. Across the galaxy, in the seat of power on Earth, Space Commander Travis – who hunted Blake before his capture by the Federation – warns the newly-promoted Supreme Commander Servalan that Blake is more of a threat than the Federation’s strategists think he is.
Now with Vila and Gan aboard the ship, Blake turns his attention once more to gaining control of his new transport – which means he has to trust Avon, who may or may not be trying to gain control of the alien ship for himself. As Gan and Vila explore the depths of the ship, no doubt seeking treasures worthy of plundering, they stumble upon one of the control core areas for the ship’s computer, and Gan is ensnared in the ship’s organic machinery. The ship, which is seeking candidates for a replacement crew, scans Gan’s mind to learn the identities of Blake, Jenna and the others, but still finds only sketchy information and sets itself on a course to collide with a star. Avon tries to reason with the computer, while Mezin takes advantage of the chaos to try to signal a Federation ship for help, an act of desperation which instantly loses her crewmates’ trust. The alien ship blows the Federation scout away – but not before forcibly extracting information on Blake and the others from the scout ship’s database. Even as the ship’s sentient computer repeatedly demands that Blake and his fellow fugitives must submit themselves to an initiation procedure, Avon warns that they may be dealing with an unstable mind at the heart of the ship. Jenna suggests an old smuggling haven of hers for a temporary hideout, but when they arrive, they discover that the Federation has razed the planet’s entire civlization to the ground. Blake decides to drop Mezin off there, but when she sees what has been done by the government to whom she has pledged her loyalty, the Federation officer starts to come around. Christened the Liberator, Blake’s alien ship decides that it needs to refuel – and the supply depot at a heavily populated Federation colony becomes its first target, despite the crew’s wishes. The resulting “attack” now puts the ship and its crew somewhat higher on the priority list for Supreme Commander Servalan and Travis.
In the wake of the Liberator’s attack on a Federation fuel refinery, and with no idea who is aboard other than Mezin, Travis is given more authority by Servalan to find the ship and protect Federation interests. But Travis’ idea of containing the threat is very different from that of his superior: Servalan wants the Liberator captured so she can use it as her personal flagship, ruling the Federation with an iron first. Travis simply wants the ship and its crew destroyed – a more effective way of dealing with the threat, and one that won’t involve the loss of men and equipment that a boarding party and a running firefight with an unknown crew armed with unknown weaponry would entail. But in Travis’ next attack on the alien ship, Liberator’s true commander is revealed – and by default, his mission can be nothing less than toppling the Federation. Aboard the Liberator, Blake has problems of his own as Avon and Vila put a plan in motion to mutiny against him, angry that they’ve effectively been branded for life as members of Blake’s revolt. Jenna quashes the mutiny just in time, and Avon and Vila are given the opportunity to leave Liberator with no questions asked…though now that their names are linked with Blake and his ship, they know there’s nowhere to run. Travis mounts a surprise attack with devastating results, but both he and Blake are surprised when new ships join the battle – alien ships, just like the Liberator. And they’ve come to recover their lost property.
Years before the joined the Liberator, Vila and Gan weren’t even friends – though they did become uneasy allies when Gan, a hired hand for the wealthy owner of a secretive business venture, recognized that Vila’s lockpicking skills could help him (albeit indirectly) win the affections of the girl of Gan’s dreams. Gan and Vila set out to pull off a daring heist that could make them both rich – but it involves stealing from Gan’s own employer. Two things happen that Vila and Gan weren’t counting on: Gan’s employer turns out to have top-secret Federation military ties, and a taste for lethal automatic defense systems to match. The other wild card is the rioting that begins when the results of the vote for the President of the Federation are overturned to keep a man called Roj Blake from winning the popular vote. With chaos looming in the background, Vila and Gan have found either the best possible cover to pull off their caper, or the increased police presence will make it much easier for them to be caught and shot on sight…
