I thought this might be a spooky witchy occult book, which it was in lots of ways, but it was also a gorgeous found family queer story set at a time when such found families were looked up derisively. The book is set in 1991, while America and the world still reels from the impact of AIDS at Blackfriars School for boys in the fictional town of Adders Lair in Massachusetts. It was a book that was shocking, scary, joyful, funny, sexy. Any superlative you can think of probably applies here.
