This is a really good book. Here is the general plot: The Vespers have already come out. They’re ready to fight. Nobody knows who they are, and if they can be handled. Amy and Dan aren’t ready. They can’t have expected the clue hunt. They can’t have expected it to change them. And now, with their normal life back, they’re not ready. Now Amy and Dan are expected to keep something safe. A Madrigal treasure…. I really liked this book.
