Mockingjay by Suzanne Collins?

that was the most emotional book ive ever read, andi was wondering, why did she make it so peeta wasnt really "him" and lost basically all of his memory, it pissed me off, like all of that stuff they've been through, gone. and also, why did they kill finnick! i cried forever after that, especially for annie, and, im still bummed for that crap
