In Linda Cajio's wonderful tale of passion reignited, a pair of ex-lovers make a running start toward overcoming the barriers that have long divided them.   Kate Perry's well-ordered world goes topsy-turvy when she brings a stray tabby to the vet with an injured paw. The doctor on duty is her ex-husband, Mitchell Jones, and seeing him again reminds her of the ecstasy--and agony--they once shared. But ever since her divorce, Kate finds that intimacy has just been too painful. So she avoids it at all costs--despite the way her body reacts when she gets too close to Dr. Jones.   One look at Kate tells Mitch that the heat between them remains, although there are some major obstacles to winning her back. His disastrous second marriage--to Kate's high school rival--may be over, but it left him a single father to a daughter who needs him more than ever. Besides, Kate's different now, sharp and businesslike. But underneath the tailored suits and high heels, the fun-loving Kate is in there somewhere, and Mitch will find her again . . . no matter what it takes.
