If you're a fan of YA books and silently sobbing, you're going to love the trailer for If I Stay. Chloë Moretz stars in the adaptation of Gayle Forman's novel as a young cellist who falls in love with a local punk rocker (Jamie Blackley). When she gets into a tragic car wreck with her family, she has to choose between waking up to the boy she's in love with or letting her life slip away. I'm not going to lie; this trailer is intense. Everything is all butterflies and roses, and then suddenly she's an orphan and floating outside of her comatose body. Then "Say Something (I'm Giving Up on You)" by A Great Big World swells up, and all bets are off. The movie opens Aug. 22, so you have until then to stock up on tissues.
