She's his best friend's sister, but he's ready to break all the rules...

Country veterinarian Celia Gamble is in trouble. A misunderstanding from her past is rearing its ugly head and the only person she can turn to is Jonah Clarke—her family's lawyer and, as it turns out, her brother's best friend and her childhood crush. She always wanted Jonah to see her as a bona fide woman, but as a woman who's being blackmailed for seducing a married man? Not on her life.

Jonah is happy to help Little CeeCee Gamble, if only she'd come clean about why she's being blackmailed. But with his best friend Zach's wedding on the horizon, and Zach's fashionista fiancée Desiree giving CeeCee a makeover, the little duckling Jonah remembers is turning into a definite swan. And the unwritten law on sisters is clear—hands off. Jonah must resist or lose the only true family he's ever known.
