Daniel's father dragged him to Leisure World for a little holiday--something to do after Daniel caught his mom cheating. The sports-averse Daniel would rather be nearly anywhere else, until he meets Lexi. Lexi is beautiful, and smart, and troubled: every day, her wounds get a little worse. She won't talk about it, until Daniel gets caught in the same loop: (view spoiler)[2 years ago, she was dragged into the woods and killed; now she lives each year in reverse until that one Daylight Saving hour, when the clocks get turned back and she relives her attack. (hide spoiler)] The only thing in Daniel's future is changing Lexi's past. 
 Creepy and atmospheric, though predictable. (Maybe if I were in the target demographic and didn't have ~30 years of Reading Creepy Stories under my belt I'd have felt differently.) I cared about the characters and wanted to see things work out for all of them--even the background characters, the neighbors and the father, are people and not just cutouts. It's creepy but not outright scary, with some gory descriptions of wounds, but nothing the average 14-year-old can't handle.
