Welcome to House of Horror!!! Hill House books are a great place to start on DCUI. We have previously read The Plunge and Basketful Of Heads. If you are in an adventurous mood you can check out the list of every book we have read. There are some out-of-the-box picks (Action Comics) and many titles that often get overlooked like The Dark Mansion Of Forbidden Love.
I agree, that ending was perfect!!! I honestly did not see it coming so when it happened I was extremely happy.
