Prodigal Son by Lydia Michaels

Bestselling author, Lydia Michaels, weaves a ferociously addictive tale of immortal hunger, lust, and noble sacrifice in the haunting continuation of The Order of Vampires series.

Cain Hartzler has a tortured past and a score to settle. After losing his destined mate, he is sentenced to an eternal life of pain and solitary sacrifice. To serve a purpose, he enters a deadly crusade to hunt and destroy the lethal vampire butchering mortal females in the Pennsylvania woods. But his honor is put to the test when the meddlesome news reporter, Destiny Santos, gets in his way.
Foolish ambition drives Destiny into the woods, but rather than find a lead, she discovers a sinister army of feral vampires out for blood. Desperate to escape, she shoots the one immortal willing to protect her from certain death.

As sinister vampires close in, Cain has no choice but to take the blood of the human female to survive. Mortally injured, he must escape the woods alive, or break his greatest vow.
