The do-over
(Book)

Sixteen-year-old Emilie, stuck in a cosmic Groundhog/Valentine's Day nightmare where she discovers her family is splitting up and her boyfriend is cheating on her, decides to embark upon The Day of No Consequences, but when her repetitive day suddenly ends, she must face the consequences of her actions.

After a dumpster fire of a Valentine's Day, Emilie Hornby escapes to her grandmother's house for some comfort. She passes out on the couch, but when she wakes up, she's back home in her own bed-- and it's Valentine's Day all over again. And the next day. And the next. Emilie is stuck in some sort of time loop nightmare: re-watching her boyfriend, Josh, cheat on her day after day. And she keeps running into Nick-- sometimes literally-- in unfortunate ways. When something good starts to come out of these terrible days, what happens when the universe stops doling out do-overs? -- adapted from jacket
