Boys Can't Be Witches - Lee French - Bog

Portland has a witch problem.
Claire expects Christmas vacation to deliver an earned respite from thinking, doing, and obeying. She gets to sleep in and play with dragons. Right? Of course not. Ghosts don't care about vacation.
Drew wishes magic could finish high school for him. Who cares about calculus or dangling participles when he can crush mutant bugs with his mind? It can't do much more, though, until he gets off his butt and learns how to use it properly.
In this fifth and final installment of the SPIRIT KNIGHTS series, Claire and Drew find out what happens when they spend three weeks ignoring the obligations of the power at their command and live a normal life.
Spoiler alert: nothing good.
