About the author
Isabel Cooper lives in Boston, Massachusetts with her boyfriend and a houseplant she's managed to keep alive for over a year now—a personal best. By day, she's a mild-mannered editor at a legal publishing company. By night, she's really quite a geek: polyhedral dice, video games, and everything. She only travels through time the normal direction, and has never fought any kind of demon, unless you count younger sisters.
