The Mermaid King [EPUB ebook] 
An Act of Piracy Short Story

There are beasts and creatures full of magic in the world and Araceli has seen her share. She has a spirit of blood living inside her body and one is enough. She fought for her freedom from slavery, fought to become captain of the pirate ship Justice, and fought the spirit in her body for control. And after all that fighting all she wants is an easy little treasure hunt with her best friend, Kyros and his lover Erik

But Kyros doesn't find easy treasure and this little chest buried in the sand may connect these pirates with the most powerful magic yet.
