I've been keeping a secret . . . There is a fourth Shadow House book coming out in August 2018!
The title is THE MISSING, and it's a stand-alone story set in the world of Shadow House with a whole new cast of mysterious characters. If you pay close attention, however, you might see some familiar faces from the original trilogy.
