Jefferson Manor by Elexa Wood:
 
Rocky River, Wyoming is an eerie quiet town. The iron clad shutters on the houses creepily close on Halloween, locking everyone inside for the night. But it only takes one Halloween to change this forever.

Levi, Henley, and Ava's senior year is finally approaching making them eligible to participate in the drawing for the Halloween Haunt at Jefferson Manor.

An innocent game of hide and seek has them shivering in hiding spots and listening for every sound, one minor mishap could end it all.
