If I Die is just what the title says: what will happen if Kaylee dies? The entire book spans one week in time, and focuses on her name coming up on the reaper list. The focus of the book is saving Kaylee's life, well, at least for her friends (namely, Tod) and family (namely, her father). For Kaylee, she doesn't want to trade her life for anyone else's---her mother already traded her death date for Kaylee, and she doesn't want anyone to die for her again---so she decides to make the most of the few days she has left. 
 But, before she can start on her bucket list, a new threat pops up. Kaylee and her friends learn that the good-looking new teacher is actually an incubus who is trying to procreate with students at school. This is no normal pregnancy we're talking about---babies spawned by this incubus often kill the mother. Kaylee embarks on a mission to rid the school of Mr. Beck, with the help of Sabine. I enjoyed getting to know Sabine a little better. She really grew on me in this book. I love her openness and honesty.
