Key, luckily, is pretty well preserved. She also feels that her memories lie just beneath the surface, and as though she can remember who she is. Drawn to Smoke (found with cigar and fancy cigar holder) and Journal (found with his journal), she feels that she can solve the mystery of Under which the others have been resigned to live.
The only way to die in Under is to be burnt to ashes. When bodies begin showing up burnt with their tongues cut out, Key will need to solve the mysteries not only of Under itself but also of the murderer, before it is too late.
This was a quickly moving and mysterious book with an element of horror (from the descriptions of people and the murders) that follows Key as she begins to dismantle the unknown through slowly arriving memories and searching. While the mystery is deliciously slow, the book reads very quickly as it is hard to leave Under without knowing the truth. The ending is left rather open, and we do not find the final end to the story- I would have liked more closure, but I understand why it was left as is.
Overall, this was a creepy and quick read that had me rapidly turning pages to learn more about Under and about its enigmatic residents. Readers of YA mysteries who like a touch of horror will enjoy this engaging fiction.
