The Heart of Hendrix: A ShortBook by Snow Flower

Hendrix has run from the D.O.D. (Dept. of Divergence) her whole life, never making lasting connections. She can't afford to with her unusual mix of fae and shape-shifter blood. After she hits a deer on the road - that turns out to be a shape-shifting tribal leader - her fae blood compels her to save his life. Unfortunately, he's running from hellhounds. With both the D.O.D. and the hellhounds on her trail, her life is in even more danger, but will her heart let her keep running?
