I'm so sad to come to the end of this series! Real tears for the Lockes of Lovecraft! Now I want to go make jewelry from old keys. I wouldn't want to give anything specific away, but this volume is a super climatic, action-packed, heart-wrenching conclusion to the Keyhouse gang which actually doesn't leave you feeling hopeless at the end. Also, Rufus has an amazing comeback and all the main characters get lots of face time. I need to own these.
