The Great Museum Mix-Up and Other Surprise Endings (Ruby Starr, Bk. 3)

Ruby Starr is feeling fabulous after helping save her school's library and creating the world's first (and best) pickle cupcake. And she's feeling extra stupendous when she's assigned a book report and finds the most incredible, meant-to-be-book ever—one about unicorns!

But when her bestie is not acting like herself, and a class field trip to a museum doesn't go the way Ruby imagines, Ruby's not sure she'll get the perfect end to the year that she was hoping for.
