Gone to the Dogs — Mary Guterson

Rena never meant to steal her ex-boyfriend's dog. She was just casually driving by his new house, taking stock of his new life, when the dog invited himself into her car...Okay, so she stole the dog. But how could Brian, her boyfriend of seven years (not to mention "unofficial" fiance), have done this to her? Fallen off the face of the earth, only to resurface with a gorgeous, live-in girlfriend and live-in dog? Honestly, a girl can only take so much. Besides, how could a yellow lab as great as this one be happy living with those two very bad people?
Unfortunately, being a dog-napper is the least of Rena's problems. Her mother's dating a "potential" serial killer, her sister's having an identity crisis and she's the target of one hopeless fix-up after another--most recently, the highly moral Chuck, who just happens to know all about Rena's dog-napping escapades. If Rena wants to straighten things out, she'll have to face up to the choices she's made, the dreams she's put on hold, and the man who broke her heart.
