Gabby Greene: Secret agent. Mother of two. Figuring it out as she goes along.

After her divorce, Gabby never expected that she'd be this close to having it all. Spying with a hot handler who's an expert in after-hours under-the-covers work was not on her current bingo card. But balancing romance, espionage, and school lunches is a job for a magician, not a secret agent. Gabby will just have to keep dreamy Markus at arms-length . . .

Easier said than done. Her next mission, should she choose to accept it: Pretend to be Markus's fiancée so they can infiltrate a Power Couples Retreat to see whether the group is selling national security secrets (in addition to questionable beauty products).

To avert a national crisis, Gabby and Markus will need to look like they're in love, planning their wedding--and enjoying the honeymoon cottage. Faking a relationship with the perfect man without actually falling for him? Piece of calorie-free cake, right?
