Making My Vampire Master Beg For Mercy

Lem is an ordinary weapon, forced by the mark of thrall on his forehead to obey his cruel master's every command. His life changes in an instant the day his master is killed, leaving his master's spoiled yet beautiful daughter to inherit her father's weapon. Now Lem must prepare for a whole new type of cruelty - attending school as an enthralled bodyguard to the wealthy heiress. His only hope of escape lies in rumor, for it is said that a thrall who can make their master beg for mercy will find themselves unbound and returned to the life of a normal human.
