After imbibing in one too many Banana Bamboozles at a backyard party, Cassidy Dunne is flabbergasted to recognize one of the partygoers as her teenage niece. When she points out the girl to her longtime best friend, Dan Diehl, he revokes her bar privileges, reminding her that one, she's blotto, and two, the niece in question died in a tragic house fire as an infant fourteen years earlier.

Nevertheless, Cassidy becomes obsessed with confirming the girl's identity, regardless of possible disastrous consequences.

Dan has been involved in thirty years of Cassidy's bad ideas, but gets sidetracked by an accusation against him with the potential to destroy both his business and his reputation. Cassidy must handle this one alone.

Well, almost alone. Every problem in her life is accompanied - and medicated - by her secret stash of candy. Run-ins with an old high school nemesis. Booty calls with her ex-husband. Her first date in Justin Bieber's lifetime. Shapeware. All tamed with a candy bar. Or three.

But all the chocolate in the world can't help her figure out this puzzle. If she's not prudent, she could ruin several lives.

And Cassidy isn't prudent.
