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 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 freezes up at his first cross-country race, causing an accident that leaves Antoine with a busted ankle, he’s 100 percent sure he’s cursed. David wishes he could do it all over. He doesn’t expect his wish to summon a pushy, annoying talking dog who claims to be his new timeline guide. According to Fea, somewhere in his past, David made a choice that put his life on the wrong track. And she can take him back to fix it. David knows exactly what he wants to undo: the accident that hurt Antoine. But when his first try (and the second, and the third) is a total disaster, he 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.
