The D.O.A. series should be read in standalone, but you really should read them in order to understand the characters.
Rylee had no idea where his life was going. He had a job he hated, a mate that wouldn't make the move to claim him, a dragon that seemed to dislike him immensely, and his brothers were so busy with their own mates he had no one to talk to about any of it. Instead, Rylee made some hard decisions on his own. One of which could cause him to lose everyone he holds dear...including his own life.
Taj had no idea what was going to become of his mate and himself. Rylee still had not said he wanted to make their mating official, his maharishi wasn't helping him woo Rylee in that direction, and now Rylee decided to defend a member of a rival biker gang accused of murder.
Spirit had no idea how to talk to a human but knew he had to figure it out quickly. He had Taj's dragon heat getting worse every day, Rylee putting his life in danger trying to prove himself to no one but himself, and he had to do everything he could to keep both men alive so they could become one.
Will these three find the answers to their dilemmas, or will they take too long and lose whatever chance they have to become one?
