Blue Noon (Midnighters Series, Book 3)

The Midnighters have emerged victorious from their greatest challenge - They now know much more about the secret history of Bixby and, with the halfling dead, the Grayfoots' link to the darklings has been severed - Rex's horrific experience in the desert has left him damaged, painfully suspended between light and dark - It seems the walls between the secret hour and real time are crumbling, and soon the dark creatures will break through to hunt after centuries of waiting.
