Martha Beckett's life is over, or so it feels after her father moves her from California to Illinois in the middle of her junior year of high school. But on her first day in her new school, she finds a peculiar boy waiting for her. James is cute, friendly, and obviously too good to be true. Her skepticism proves justified after he confides in her his secret: after he dies, he is reincarnated as himself to live his life again and again and again... Retaining all knowledge and skill acquired in his previous lives and with a general understanding of future events, James is effectively superhuman. And while Martha enjoys the inherent perks of associating with such a boy, she comes to learn of the despair and exhaustion underneath it all. With no permanent consequence or hope of release, James struggles to stave off nihilism with Martha his one tether to humanity.
