When Sylvia Carson is sent off to her reclusive, absent–for– 20-years, outcast aunt, she expects her summer to be boring, devoid of fun or adventure and haunted by the stories her family has told her over the years about the woman who took off at 18 and never came back. The last thing she expects is to be introduced to a world of magic, monsters and danger, where one mistake could cost her the world. Coincidentally, Sylvia has already made that mistake.

Oops.
