Middle school is the worst, especially for David Bravo. He doesn’t have a single class with his best (and only) friend, Antoine. He has to give a presentation in social studies about his heritage, but he’s not sure how, or even if, he wants to explain to his new classmates that he’s adopted. And after he injures Antoine in a cross-country accident, he just wishes he could do it all over. He doesn’t expect his wish to summon a talking, annoying dog, Fea, who claims that a choice in David’s past did set him on the wrong timeline…and she can take him back to fix it. But when their first try (and the second, and the third) is a total disaster, David and Fea are left scrambling through timeline after timeline, trying to figure out what she’s really here to fix—a quest that may lead them to answers in the most unexpected places.
