I loved so much about this book. The Avicen (bird-like magical humans) and the Drakharin (dragon-like magical humans) are fascinating in their history, cultures, and features. It makes me want to have feathers for hair. And the characters are great: consistent, well-written, and hugely likable. As a New Yorker, seeing magic in so many well-known museums and libraries is also always a treat. I know New York is an easy target, but it’s still fun, along with some less-known corners of Japan, Germany, and so on. These folks definitely know how to travel. All in all, an engrossing and exciting YA adventure.
