Seven Year Witch

Ava Reskin is a highly trained supernatural assassin. A lean, mean killing machine who's always looking for the next job. Until a mix-up at The Organization sends her to the last place she wants to be -- the fairy godmother division.
Now she has to survive the Fairy Makeover Squad, a satin ballgown, and -- gasp -- heels. The only perk to the job is her new assignment. The very sexy Craig Harper, who seems more interested in what's under her dress than what wishes she can grant for him. There's only one snag she can't seem to overcome -- the secret fantasies she's always had about Vic, her former boss. The choice is impossible... until she realizes she doesn't have to choose. She can have them both. In fact, they really would prefer it that way.
