Lucy Usthorn of Fort Worth, Texas, is super excited for her class trip to the Natural History Museum. Sure, Ms. Brock, the strict school librarian who happens to be dating Lucy's dad (awkward) is chaperoning. But it'll still be the best day, right? Wrong! Lucy watches in shock and humiliation as her dad proposes to Ms. Brock. Lucy is distraught. If only she could do this day over from scratch... Enter the magic bracelet. It arrives in the mail, with a letter from Addie, the girl who had the bracelet before Lucy. The bracelet grants wishes, and Lucy knows just what to wish for: a do-over day, where she'll fix everything and stop her dad's proposal. The wish comes true but not quite as Lucy expected. Her day keeps repeating over and over! With the help of her new long-distance fiends, Addie and Becca can Lucy figure her way out of this time loop?
