The Eternal Sea by Angie Frazier
Romance and adventure are just around the corner . . .
After the thrilling journey that led Camille through the dangerous discovery of love, secrets, and a magical stone that grants immortality, Camille has everything she wants. She's escaped the men who wanted her dead, and now she is ready to build a new life with Oscar, her one true love. But things are not to be so simple. Oscar is acting strangely, and before they can even board a ship from Australia back home, to San Francisco, Camille learns that the journey is not over. If she does not follow the magic of the curse of Umandu, her life and Ocar's could be in grave danger.
This book is actually Book #2 in the Everlasting series, the first book being--well, Everlasting.
Isn't the cover to die for! Everything about it is incredible from the colours to the way the girl stands alone with nothing but the lantern to light the way. It's absolutely beautiful and I can't stop looking at it.....
