I read and loved the first book in this series, Dante's Wood. Dante's Poison is a fine follow-up---twisty, turny, complex until all the threads come together. I would still recommend reading DW first to have the full story of Mark's blindness and family regrets, but this book made Mark more real to me. He's less angry, more human. I can see rooting for this character for a long time, through many books.
