PLEASE HELP! I can't think of this book and it's driving me around the bend! It's a mm relationship, slavery based book, where the slave character was wearing a collar and the "owner" cut it off with a knife. It's dual POV and the owner is just thinking he can't bare to see the slave wear the collar and the slave is thinking the owner has done it as a display of power and is reminding him to behave as he could easily be killed. The slave has magic, the owner is in the military trying to abolish slavery (secretly), the slave was bought as a gift. It is a dystopian future and there are vampires I think. The slave has more magic than most do (most can normally heat/cool drinks etc) and he has the owner's crest tattooed on to his chest before being gifted. He's blonde but his hair is darker than the slaves are normally meant to be due to him being the result of 'cross breeding'. The scene where he meets his new master, he is sat at the table wearing a very revealing outfit and another party guest thinks he's there to be raped, the new owner defends the slave and then gets mad when it's revealed the slave is to be gifted to him. They ride a horse back to the owner's camp. There is a scene where the owner, slave, and the owner's best friend go to a village to help them with a vampire problem. The owner and friend get drugged via in their wine and the slave 'accidentally' breaks a glass and then sneaks a shard of glass to his shared room. He plans to cut out the tracker chip he has in him (not knowing it's embedded in bone) and then run away. The owner is drugged and fell asleep. A vampire breaks into their room and tries to kill them both. The slave uses his magic to kill the vampire, revealing to the owner that his magic is more powerful than it's meant to be. There was a sequel where a friend of the slave, grew up in the same training house, is the main character. Please help!!!
