When Thea Wyndham and Mitchell Baker learn they've been named joint guardians for their late friends' three children, they're little more than acquaintances. Barely polite acquaintances, at that. Something about Mitch's forthright intensity has always left ad exec Thea feeling off-balance, while Mitch makes no secret of his disdain when Thea offers him financial assistance if he'll take sole guardianship. Thea is far from heartless. She's just plain terrified of her new parenting responsibilities. Both she and Mitch are romantically involved with other people. Yet the more time they spend together, the less certain she is of her loyalties. There are complications and missteps, tears and laughter, lots of it. And somehow, through it all, the dawning realization that the last place she thought she'd find herself could be just where she belongs.
