Threads of Ranic — C.E. Martin

An epic battle will rage between two sons of Cyrus...the victor will determine Earth's future.
Charlotte is searching for a runaway dog when a man drops from the trees. His pull on her is more than physical -- and might be dangerous. When she discovers Elyian is actually a vampire king from another planet, Charlotte has to decide whether to ignore her new-found knowledge to keep her stable life, or leave all she knows to explore a new world with a complete stranger.

Then she meets his father…

Elyian's planet, Ranic, is in trouble. The evil Havvol is intent on killing Elyian and taking over both Ranic and Earth. When Havvol discovers a secret about Charlotte, she becomes his new obsession. Will Elyian and his father be able to set aside their own desires and jealousies to stop Havvol from destroying not only the woman they both love, but also two entire worlds?
