A different book by the author of the Kronos Chronicles – Cabinet of Wonders, The Celestial Globe and The Jewel of the Kaldrash. This one is about parallel worlds and a young woman who is living in our world, not knowing she is not of our world. A new guy starts at school and she falls for him, only to have him arrest her and take her back to her world. It is a world with humans and shades. Shades don’t have to eat, can disappear at will and live a lot longer than humans. There is currently an uneasy peace between the humans and shades but it will not last, the humans want revenge for a shade attack on a hospital where innocents were killed. Darcy, the girl who doesn’t know she is a shade, finds out and starts to learn about the things she can do. She has to report to Conn (the guy from school who turned out to be a law officer in the parallel world) but feels like she can’t trust him or the shades. She inadvertently finds out about a new shade attack and tries to prevent it. This is a great read, lots of action and a look at relationships and trust and versions of the truth.
