Hallow's Eve

"... with love, a certain type of hatred followed."

The summer Parker Hadley's little sister disappears is the summer that changes everything. There are no clues, no leads as to who took Quinn Hadley. One moment, she was sound asleep in her bed. Then, she was just gone.

Parker doesn't believe in coincidences. There are explanations for everything, and things tend to tie together. Then she meets the people who can find her answers once and for all: Maddox, a boy famous for his ability to locate missing objects; Jamie, a boy whose bark is as lethal as his bite; and Caleb, a boy with a secret that has been hidden for centuries.

Maddox agrees to help, but under one condition: Parker has to help him find his mother, the one thing he has been hunting for his whole life.

Which turns out to be a lot easier said than done.
