Shoots to Kill by Kate Collins is the seventh book in the “Flower Shop” mystery series.  Publisher: Signet, August 2008

Eight years ago, Abby Knight babysat for a problem teen named Elizabeth. Today, Elizabeth’s back, with a new name (Libby) and a whole new life (stolen)—namely, one that already belongs to Abby. Libby’s even trying to steal Abby’s boyfriend, Marco. But imitation really becomes the sincerest form of trouble when Abby finds herself the accused dupe in a bizarre murder plot.

I enjoyed this story which is about someone from Abby’s past steals her identity as well as her life.
