Adam Rivers is about to be sacrificed to the bloodthirsty dragons for the crime of not paying his debts. Instead of being eaten alive, he wakes up as he's being touched in the most wonderful way he can imagine. Someone he knows, someone familiar, is on top of him, loving him, and claims that Adam belongs to him. Adam, not knowing what is happening, but just happy to be alive, willingly gives in. His new lover is the very dragon who spirited him away. Novik Gray claims to love and adore Adam, and that he will do anything to protect him. Adam recalls saving Novik's life ten years earlier, but is Novik simply confusing gratitude with love? All Adam knows is that he wants to stay by the man's side, but when a friend is put in danger, Adam will be forced to test just how much Novik truly claims to love him.

Adam Rivers is still getting used to life as being the only human mated to a dragon in an enemy nest. His lover, dragon warrior Novik Grey, is always accommodating, even if there are others who want to see Adam gone. After Novik rescues a friend of Adam's, tension in the nest rises, and the humans are considering going to war against the dragons. This is enough to cause a lot of stress and anxiety throughout the dragons, and Adam doesn't want to complain, even when a few people come a little too close, sound a little too threatening. Adam wants to take some of the load off of Novik's shoulders by handling this himself, by proving that he doesn't always have to rely on Novik to save him. When the dragons get together and form a plot to get Adam out of the nest, without his or Novik's permission, Adam might just be a little in over his head.

Blue has never been anything other than a servant, a slave to cruel masters. When rescued accidentally, he didn't expect his new good life to last, and it didn't. Returned to his former masters, who want their property, Blue doesn't expect to even survive the night. He especially doesn't expect dragon warrior Lightning to come for him. Blue is nothing, and yet Lightning refuses to leave without Blue at his side, even if it means causing a war between the humans and the dragons. Lightning has been in love with Blue ever since he first saw the man, though because of Blue's former life, he kept his distance. Lightning didn't want to risk that Blue would see Lightning's attention as another form of manipulation, but now there is no choice. Someone took Blue from the nest, and Lightning will destroy everything in his path if it means getting his blue-haired mate back where he belongs.

Lord Dravick Grey is the dragon king of his nest, and desperately in love with the human servant who fills his wine goblets during dinner. Aaron is a favorite, and though he cannot make it known to anyone, even the man himself, that does not stop him from secretly meeting him again and again in his bed chambers for nights of pleasure. Though Dravick would love nothing more than to make his love for the man known, recent attacks and traitors within his nest make that impossible. If he were to announce his love for a human, the dragons under his command would rise up, and they would take their anger out on Aaron. He might be too late, however. Someone has learned the truth and has gone after Aaron in a bid to make him suffer for the crime of being with the king, and Dravick will make them suffer for it in return…

Jason Foreman spent the last several months dancing around the strange relationship he has with Dragon warrior Kraigan Snow. First he can't stand Kraigan, his threats or attitude, but then Jason loves nothing better than to tease the man and stay close. After Kraigan saves Jason's life, he's started to look at Kraigan in a whole new light, and the way Kraigan kissed him isn't helping his growing fantasies. Kraigan wasn't sure when it happened, this feeling he has for the annoying human that built into lust, but now he wants Jason, desperately. When Jason finally gives in, Kraigan's feelings, the ones he'd buried so deeply he'd forgotten they existed, grow so quickly that he pushes Jason away. But it's too late. He loves Jason, that bratty human with the smart mouth, and he might be too late to confess it to the man after Jason is attacked by a radical who wants humans and dragons to stay separate forever.

Human servant Jason Foreman has finally gotten together with the love of his life, dragon warrior Kraigan Snow. Their rocky love-to-hate relationship nearly ended the both of them before they realized their true love for each other. Now that they are together, there are new hurdles to face. Kraigan knows his mate is uncertain, but he does not know how to comfort him, and can only hope to keep him safe with his actions. Jason knows that Tatsu, another dragon warrior who is in love with Kraigan, still believes that he is not worthy of being mated to Kraigan because he is a human and a servant. With that, on top of the fact that Jason can never give Kraigan a child, Jason finds himself struggling against the breaking point as both men fight to keep each other before they're torn apart.

Tatsu Lung, powerful dragon warrior for his nest, has to get over the fact that the man he secretly loved was in love with another. Not easy to do when he's stuck in bed for weeks with an injury, but the cute human healer is interested in taking away his ache in more ways than one. Nathan Price thought he was a human, until one amazing night spent with Tatsu revealed the truth. He's part shifter, maybe even part dragon, and now he's got a dragon child growing inside of him. He has to tell Tatsu, and he isn't looking forward to letting the man who does not love or care for him, know that he's about to become a father. Nathan isn't prepared at all when Tatsu insists on moving Nathan in with him, and since Nathan is a human, or at least part human, in a nest of dragons, he has no right to say no.

In the conclusion to the Dragon Hearts Series, Adam and Novik are having trouble finding some alone time together after the birth of their son, and another recent attack by the humans, and the dragons within their own nest, haven't been making things easier for them. Adam misses the intimacy he used to share with his mate, but rarely sees him because of Novik's duties as the leader of the dragon warriors. Adam is determined to get the time they need to reconnect. Novik has no problem with this, but it seems his duties to protect the nest have him returning home too exhausted to do more than fall into bed, let alone see his mate and child. He's determined to make this work one way or another. However, a familiar enemy will make one last attack on the nest, going after every human to have ever vexed him, and it might put Adam and Novik's plans on hold indefinitely.
