The Big Sigma Series is a science fiction adventure written by Joseph R. Lallo, author of the Book of Deacon and Free-Wrench.

This anthology, set approximately four hundred years in the future, shows the state of the galaxy through the eyes of a marvelously skilled but terribly unlucky former racer named Trevor “Lex” Alexander. It collects three full novels of his adventures, describing his rise from the ashes of his own poor judgement to repeatedly become the lynchpin in missions with dire consequences for failure. The stories are often comic, sometimes dark, but always thrilling as Lex gets mixed up with the likes of mad engineers, quirky AIs, loose cannon mercenaries, faceless megacorporations, and organized criminals.

In The Big Sigma Collection: Volume 1 you get three full novels:

Bypass Gemini - In a distant future, Trevor "Lex" Alexander was shaping up to be the next great race pilot until a fixed race got him banned from the sport. Reduced to making freelance deliveries, he thinks his life can't get any worse. That's when a package manages to get him mixed up with mobsters, a megacorp, and a mad scientist. Now his life depends on learning what their plans are, and how he can stop them.

Unstable Prototypes - Eight months have passed since the Bypass Gemini incident, and Karter Dee - a brilliant inventor and dangerous sociopath - has been kidnapped by group of desperate extremists. To prevent the group responsible from unleashing Karter's lethal ingenuity, the inventor's quirky AI "Ma" convinces ex-Racer "Lex" Alexander to help assemble a team of former allies in order to mount a rescue.

Artificial Evolution - Third in the Big Sigma series, Artificial Evolution begins with our heroes facing the bureaucratic wrath of VectorCorp. Thanks to a vindictive corporate operative, Lex is without a reliable job and Michella's network won't support her investigations. Checking out a supposed alien seems to be the perfect cover for some subversive journalism, but it might turn out to be her biggest story yet.

In addition, you’ll get three shorter works never before available:

Squee’s Day Out – An unlikely short story about Squee the Funk’s mischievous adventure while Lex and Michella are away.

Building the Perfect Pet – The untold story of how Solby the Funk came to be.

Beta Testers – A novella detailing the first time Garotte and Silo worked together in an unsanctioned military operation.
