Three things I know are true
(Book)

Five months ago, Liv's big brother, Jonah, shot himself. It was an accident. He didn't know that the gun was loaded. But the damage was done. Now he won't ever be leaving their small mill town like he planned. Jonah can't speak, can't walk, can't take care of himself at all. Their house is full of machines and nurses working around the clock to keep Jonah alive. Liv's mom is struggling to cope with the aftermath, so Liv ends up being the one to soothe Jonah when he gets agitated, to lie with him when he can't sleep, and to see the carefree brother she's sure is still inside him somewhere. Liv hasn't spoken to Clay, Jonah's best friend, since the accident, even though he lives just across the street. The gun belonged to Clay's father, and Clay was with Jonah that terrible day. With Liv's mom suing Clay's father, there are lines Liv is not supposed to cross. As their entire community chooses sides, she feels the distance between them growing every day. Liv knows that Clay is nearly as broken as Jonah. She knows his life also changed forever the same moment as Jonah's. And she refuses to turn away from Clay, just as she refuses to give up on Jonah.
