Unstable Prototypes (Big Sigma Book 2)

Following his last adventure, Trevor "Lex" Alexander's life has managed to return to normal. He's back to splitting his time between delivering packages and transporting passengers, along with the occasional foray into testing highly experimental equipment. He's even gotten back together with his girlfriend Michella Modane, who has been launched to stardom by her coverage of the Bypass Gemini incident. Yes, things are going quite well for Lex. But in his life, luck like this never lasts long.

Sure enough, while he is preparing for a rare visit from Michella, he receives word that the reclusive inventor Karter Dee has been kidnapped. The eccentric and slightly deranged inventor's checkered past has made getting the authorities involved out of the question. That has left "Ma", the AI in charge of cooking his meals and reining in his insanity, with few options. She has reached out to Lex as one of the few people she can trust, and needs him to help assemble a team of Karter's former allies to take him back before his latest contraptions can be put to work terrorizing the populace at the hands of his captors.
