Hmm...I really enjoyed reading this book as an adult. However, I'm unsure if the disturbing content is eventually balanced out by the thought-provoking content to make it worthy of donating to my small school's small library. 
 When there are less than a dozen books for high school students, of course each book gets a fair amount of attention and consideration. If we had a big library, I could sneak in Where Things Come Back and trust it would be discovered by the right audience. Instead, I think of each potential reader and wager this book detailing death, disappearances, betrayal, promiscuity, small town boredom, and angels procreating with humans will only cause my sheltered, big city japanese students much confusion and angst. However, I don't want to decide for my students what might or might not inspire then. At the same time, does my headmaster want the students to dwell on overdoses and casual, sexual encounters....perhaps not. 
 Regardless, I've now purchased my own copy of The Book of Enoch as I'm curious about the story which drove Benton and his roommate to such obsessive behaviour.
