The Last Exit — Michael Kaufman

In this thrilling futuristic novel, the secret to eternal life is closely guarded by people who will do anything to protect it -- even if it means destroying everything in their path.

Set in Washington D.C. 20 years from now, climate change has hit hard, fires are burning, unemployment is high, and controversial longevity treatments are only available to the very rich. Enter resourceful young police detective, Jen B. Lu, and her 'partner', Chandler, a SIM implant in her brain and her instant link to the Internet and police records, and a constant voice inside her head. He's an inquisitive tough guy, with a helluva sense of humor and his own ideas about solving crimes.

As a detective in the Elder Abuse unit, Jen is supposed to be investigating kids pushing their aging parents to "exit" so they are eligible to get the longevity drug. But what really has her attention are the persistent rumors about Eden, a black market version of the longevity drug, and the bizarre outbreak of people aging almost overnight, then suddenly dying--is this all connected? Is Big Pharma involved?
When Jen's investigations of Eden take her too close to the truth, she is suspended, Chandler is deactivated, and her boyfriend is freaked out by "the thing inside her brain." This leaves Jen to pursue a very dangerous investigation all by herself.
