Blood Empire Avenged

Surrounded by a sea of supernatural enemies, Luke is left with nothing but desperate choices.
Luke and his werewolf friends have escaped from a vampire army. Now they're stranded in Luxembourg, surrounded by an army of werewolves and vampires. Their only hope is the Luxembourg alpha.
Luke isn't sure who to trust, but the alpha's offer of two private jets is too good to pass up. Once his friends are onboard, the Luxembourg pack betrays him, and his friends are forced to leave him behind.
Luke wakes up in a windowless stone cell. Alone. With nothing but his own thoughts to keep him company, he is left to fight his descent into madness. When a scratching at the wall interrupts his isolation, Luke wonders if it's one more symptom of his failing mental health, or some new torture devised by his vampire captors...
