About the book
The first three volumes of the bestselling detective series set in the twenty-second century by the legendary actor who played Captain Kirk on Star Trek
In the twenty-second century, mankind has expanded the horizons of science and technology. But some want to go farther. Tek takes them there. It's a bio-digital microchip more powerful and mind-altering than any other drug ever known. For those who become addicted, it's out of this world . . . and straight into hell. And only one man can stop it.
TekWar: Four years ago, Greater Los Angeles lawman Jake Cardigan was framed for dealing Tek, losing his badge, his good name, and his freedom. When he's released from cryo-prison early, his search for answers takes him to Mexico, where a rogue scientist is attempting to rid the world of Tek. Aiding this quest is the right thing to do, but for an ex-con, doing good can be the most dangerous decision of all.
TekLords: After taking down a powerful Tek cartel, Cardigan finds himself targeted by assassins and stonewalled by authorities who refuse to see the looming danger of a lethal computer virus that threatens not only technology, but humanity as well. An evil mastermind has learned how to make innocent civilians obey his commands, and he will sacrifice an army of zombie killers if it means getting a clean shot at Cardigan.
TekLab: A brutal murder on the streets of Paris appears to be but one of a string of killings around the world connected to the Brazilian wars of the past decade. But Cardigan soon discovers that the true motive behind the slayings isn't war but profit for the drug kingpins known as TekLords. As international peace hangs in the balance, he must stop the bloodshed before his old nemeses can exact the ultimate revenge.

About the book
Jack Morgan is a teenage fugitive with a price on his head. Draycos is a dragonlike alien warrior who lives on Jack’s skin as a golden, ever-shifting tattoo.
