In this amazing fantasy novel, there are two parallel universes– the one our Earth is a part of, and then the one that holds the planet of Eretz, where the monsters live. Karou appears to be a normal high school art student, but in reality, she works for a chimera named Brimstone, in a workshop that is a portal between the two worlds. As long as she can remember, Brimstone has sent Karou to collect teeth– sometimes from animals and sometimes from humans. These teeth are often given willingly, and sometimes she knows they have been procured by grave robbery, museum theft, or acts even more sinister. Karou never questions what Brimstone does with these teeth, until the day she tries to enter the portal to his shop and finds the door permanently locked, with a scorched black handprint on the front. Now, she is on the run to find her monster friends, battle an army of murderous avenging angels, and discover what the connection between teeth and wish magic really is. This first in an amazing trilogy will keep you up reading all night long!
