When best friends Skylar and Ella begin to drift apart, they try to fix their friendship by creating the ultimate BFF Summer Bucket List in this funny and heartfelt M!X novel.

Ella and Skyler have been best friends since kindergarten—so close that people smoosh their names together like they’re the same person: EllaandSkyler. SkylerandElla.

But Ella notices the little ways she and Skyler have been slowly drifting apart. And she's determined to fix things with a fun project she's sure will bring them closer together—The BFF Bucket List. Skyler is totally on board.

The girls must complete each task on the list together: things like facing their fears, hosting a fancy dinner party, and the biggest of them all—speaking actual words to their respective crushes before the end of summer. But as new friends, epic opportunities, and super-cute boys enter the picture, the challenges on the list aren’t the only ones they face.

And with each girl hiding a big secret that could threaten their entire friendship, will the list—and their BFF status—go bust?
