Odessa Green-Light still has a hyphenated last name, but her family has been de-hyphenated since her parents' divorce. Determined to stop her dad's pending remarriage, Odessa discovers that if she jumps on a certain spot in the bedroom of the house she's just moved to with her mom and brother, time turns back. The first time she goes back twenty-four hours. The next time she goes back twenty-three. Odessa figures this means she has twenty-two chances left, but that's plenty of opportunities to undo a bad grade on a quiz, erase an embarrassing moment, or be nicer to her little brother. Plenty of opportunities to make things better or to make them worse: to create some good luck (is it luck of you know in advance what will happen?), or to make her future stepmother angry in hopes she'll call off the wedding. As Odessa's chances to change things dwindle, she begins to think more carefully about what she can change, what she wants to change, and what really matters to her in Dana Reinhardt's breezy novel. (Ages 7-10)
