Sam McMillian is a tiger shifter living with a wolf pack. He was kicked out of his own family shift, not for being gay, but for being a submissive bottom. He's supposed to be a strong, fierce predator. Hiding who he really is from the wolf pack that welcomes him, Sam starts his life over. Not being able to deny what he really wants, Sam sneaks out once a month and meets with Charles Montgomery. The man is not only his Master, but is also Sam's mate. Charles is an ancient vampire. He meets his True Match, a vampire's perfect blood match, at the Silver Bullet. He hides the truth from his friends because Sam asks him to. After a year of meeting once a month in secret, Charles decides that things need to change. To get Sam's attention, Charles gives him an ultimatum, pushing the other man over the edge and provoking his tiger to rise.
