Moonbound Guardian

The imposing Fenrir McFarlan is forced to return to the north of Scotland despite not having fulfilled the last mission entrusted to him by his Sir Frederick Erskine, an ancient vampire.
But the misfortune he finds upon his arrival at the castle will unleash events for which his training and battle experience did not prepare him in his nearly three hundred years. A painful betrayal.
Suppressed revenge.
A raw necessity.
Passion and uncontrollable instincts are what the lycanthrope will have to face.
