Dragon Heat by Ella J. Phoenix

Zoricah, the draconian demigoddess, and her team of female warriors have limited time to uncover a series of killings before one of their friends meets the same fate. For that, they have no other choice but to ask for the help of her race’s ultimate enemies – the Vampires. Tardieh, the vampire king, doesn't trust dragons, but can't ignore the flames of passion that ignite between him and Zoricah.

When Tardieh, the Vampire King, discovers a letter from his late father, he opens a door to old memories. The letter from the former King Petran is a tale of romance, intrigue, attempted murder, and betrayal, but leaves more questions than answers in its wake.

Ever since she set foot on vampire territory, Samantha had turned Hikuro’s carefully controlled life upside down. He doesn’t trust her, but some strange force is pulling him toward her; an inexplicable attraction that defies centuries of training. But if Hikuro is to keep his king safe, he must keep a close eye on Sam, even if he loses his sanity and his heart in the process.

Yara, the water witch, must help her friend to overcome a strange illness before it’s too late. For that, she must go back to the only place she swore never to return – her home land. Rafe, a lone wolf, wasn’t expecting the saucy witch to cross his path and ruin his plans to get his debts pardoned. Now, he can’t get Yara out of his mind and the clock is ticking for him to make good on his word.

Descendant of a Cherokee shaman, Dyam is one of the vampire king’s personal guards and closest advisers. He has seen the worst of mankind and has vouched to stay away from personal entanglements and focus on serving his king. His resolve is shaken when Naiah, the water witch, finds her way into the busy vampire castle’s life and straight into his heart.
