Spoilers for If I Stay. 
 It's been three years since the accident that left Mia Hall as the only survivor. Three years since Mia walked out of Adam Wilde's life and disappeared to continue her life at Juilliard. Now Adam is living the rock star life. Celebrity girlfriend, paparazzi everywhere he goes, fans clamoring for an autograph. It was supposed to be everything he want, but all he can think about is her. When a chance encounter brings her back into his life, they explore the NYC Mia has grown to call home and the past and present weave together, leading them towards what could be the end and the goodbye they never said. 
 I actually preferred this book to the first. I didn't know what to expect going into it. It's completely from Adam's POV. He's struggling with the guilt of asking Mia to stay, the grief of losing her family, and the pain of losing her. He's also trying to cope with the fame that isn't really what he wants. Music and touring with the band isn't bringing him the joy he thought it would. It was a very poignant and emotional story.
