Gaelan's War

Gaelan Kelly is a high school student with loving parents, a devoted girlfriend and a promising future. When he answers the call to duty, combat leaves him emotionally and physically scarred. He comes home to a girlfriend that has moved on, and is full of self-hatred - unable to forgive himself for the actions he took after his friend was killed in combat.
Gaelan is brutally attacked during what should have been a time of healing, and is left near death. His high school mentor, Father Dennis Beaudreau, helps see him through his trauma, which Gaelan feels is penance for his actions in war. He convinces himself that the creature that attacked him was a bear, and that PTSD caused him to hallucinate.
His convictions are shattered when, a month after the attack, Gaelan experiences the agony of his first transformation. He is a werewolf and must now evade the Vatican hunters, the Benedicta Venántium, sent to kill him.
Though the Venántium continue to hunt Gaelan, he secretly assists them in hunting monsters like himself; from burrowing creatures that pull their victims to their underground deaths, to a vampire that may be Jack the Ripper. All the while, he fights the urge to commit suicide - his only motivation to stay alive is the desire to find and kill the thing that made him what he is.
Finally face to face with a pack of werewolves, Gaelan is forced to rely on the very thing he hates most - the monster within. In the end, can he become the hero mankind needs?
