Running a massively successful relationship counseling practice should guarantee smooth sailing in a girl's own love life....

Breakup Doctor Brook Ogden has spent the last year sifting through the fallout from the disastrous decision that led to her unconscious uncoupling with boyfriend Ben Garrett. Despite advising her clients you can't be friends with an ex, she and Ben have somehow begun to stitch together a friendship-one Brook hopes is slowly turning into more.

That is, until Ben introduces his new girlfriend, Perfect Pamela, a paragon of womanly virtues who is everything Brook is not. While Brook navigates her newly volatile emotional life, an unwelcome surprise shows up on her doorstep: the ex-fiancé who broke her heart two years ago-one month before their wedding.

Between her ex's desire to rekindle their attachment, her best friend Sasha's unexpected crisis, and her own unsquelchable feelings for Ben, Brook finds herself questioning the personal progress she's made in the last two years-and threatened with the highest-stakes Breakup Doctor failures she's ever faced.
