The Trinity Bleeds (The Grave Winner Book 3)

The light chases away the dark. The light commands. But the light has a weakness in its spark. A single burst of air, and I will do what the dark demands.
Tick-tock, tick-tock, for darkness is bound by mere hours. The sun will rise once more, weakening the dark’s powers. 
But at night, what is done cannot be undone, yet one last gift to the dead can restore the semblance of breath. Break the binds that tie you to death.
Tick-tock, Leigh. Tick-tock.
