I used to think my job, as a lead teacher at Shadow Lane Academy, was the most important thing in life. . . Now, I'm just trying to survive. When the Sentries-mysterious, mechanical, witch-hunting monsters-threatened the safety of the magic school, my father, the headmaster, brought in the Sentry-fighting superstar, Crew Wrathshore. But Crew brought many secrets with him; secrets about himself and why he's really here. . . The Sentries are after a specific target at Shadow Lane and they won't leave it alone until they get what they want. To protect my school, my sister, and myself, my only choice-and maybe my only hope for survival-is to work with Crew. But will his secrets put us all in danger?
