Something Wicked

Description for SOMETHING WICKED by Lisa Jackson:

Some refer to it as the Colony. To others, it's a cult. But few locals in the Oregon coastal hamlet of Deception Bay have ever been invited to the inner sanctum of Siren Song. Even the sisters, who live there, far from strangers who might recoil at their unnerving psychic abilities, don't know all the terrors buried within its walls.

This is #5 in The Colony.
