One for the money / Janet Evanovich.

Enhanced descriptions from Syndetics:

Discover where it all began--the first "snappily written, fast-paced, and witty" ( USA TODAY ) novel in the beloved Stephanie Plum series featuring a feisty and funny heroine who "comes roaring in like a blast of very fresh air" ( The Washington Post ), from Janet Evanovich, #1 New York Times bestselling author of Dirty Thirty.

Meet Stephanie Plum, a bounty hunter with attitude. In Stephanie's opinion, toxic waste, rabid drivers, armed schizophrenics, and August heat, humidity, and hydrocarbons are all part of the great adventure of living in Jersey.

She's a product of the "burg," a blue-collar pocket of Trenton where houses are attached and narrow, cars are American, windows are clean, and (God forbid you should be late) dinner is served at six.

Out of work and out of money, Stephanie blackmails her bail-bondsman cousin Vinnie into giving her a try as an apprehension agent. Stephanie knows zilch about the job requirements, but she figures her new pal, el-primo bounty hunter Ranger, can teach her what it takes to catch a crook. Her first assignment: nail Joe Morelli, a former vice cop on the run from a charge of murder one. Morelli's the inamorato who charmed Stephanie out of her virginity at age sixteen. There's still powerful chemistry between them, so the chase should be interesting...and could also be extremely dangerous.
