I'm always reading something, usually multiple books at a time.
Samantha Kingston reveals a stunning thing at the start of her first-person narrative: she has died. Sam is a popular high-school senior in suburban Connecticut, who dies a sudden, accidental death--and then finds herself reliving her last day, February 12 (aka "Cupid Day" at her school), again and again. She soon finds that she can live that day in any number of different ways, changing various outcomes and learning new things about classmates and teachers; her friends and even herself. She is not sure if she can somehow undo her death, or perhaps at least discover a sequence of actions that removes her from the loop and allows her to move on to what's next (in the event that reliving that day is not her "next").
I found this book addictive, listening to it any time I could (and also borrowing the Kindle version to read big chunks of it in text form). Recommended, especially for readers who have enjoyed other books by Lauren Oliver.
