here’s a description of the novel from amazon.com:
Jake Billings is usually cool under pressure, but when two stick-up kids rob his record store, Jake opens fire on them, landing him in prison. Five days in, he receives an anonymous letter telling him that his days are numbered. But before he can find out who’s behind the threats, Jake is stabbed and ends up in a coma.
When he wakes in a hospital bed two years later, things have changed: His prison sentence has been commuted, his girlfriend is fiercely independent, and his side piece has gotten out of the street life altogether. But one thing remains: Jake’s enemy still wants him dead and is powerful enough to track him down no matter where he hides.
On the run, and with rumors circulating about a powerful, phantomlike gang called the 300 Crew, Jake will need to rely on his mantra: Trust no one—not the law, not his girl, not the street cats he helped out years ago, not even his own blood.
