A teen tries to keep a series of unlucky events from ruining her sister’s wedding in this charming, “romantic comedy of errors” (Publishers Weekly) by New York Times bestselling author Morgan Matson.

Charlie Grant’s older sister is getting married this weekend, and Charlie can’t wait—for the first time in years, all four of her older siblings will be under one roof. Unfortunately, it will also be the last time—at least at their childhood home. Their parents have sold the house.

But that’s all the more reason to have one last perfect weekend with the whole family together. If Charlie pushes aside concerns like what college to attend and reuniting with her longtime crush Jesse Foster, she can focus on getting her mom to pay attention to the real Grants—instead of the version she draws for her popular comic strip—and making sure the house is full of jokes and games and laughs.

The only problem? The wedding is shaping up to be absolute disaster.

There’s the unexpected dog with a penchant for howling, an alarm that won’t stop going off, and a papergirl with a grudge. There are the relatives who aren’t speaking, the (awful) girl her favorite brother brought home unannounced, and a missing tuxedo. Not to mention the missing justice of the peace. The guests who are all crazy. And the wedding planner’s nephew who is distractingly…cute.

Over the course of three ridiculously chaotic days, Charlie will learn more than she ever expected about the family she thought she knew by heart. And she’ll realize that if you keep everything like it was in the past, you’ll miss out on the future.
