Sixteen-year-old Emily Haven, hero of the girls' hockey team at Lindsey High, has spent her young life keeping two secrets: her rapidly deteriorating home life and the seemingly supernatural power that makes her a star on the ice. When she begins seeing visions of a ragged boy reflected in mirrors and shop windows, a series of events unfolds that tears her from twenty-first century Minneapolis and leaves her stranded in another world with horrors to rival those she has left behind. Lost amidst creatures of fantasy and legend, she is forced to confront the demons of both her past and future to unravel the riddle of the mysterious boy and embark upon a journey to uncover long forgotten histories. Caught between opposing forces of a war she does not understand, Emily must find new strength within herself and, above all, the will to remember her friends.
