Sasharia En Garde [EPUB ebook] 

First published as two books–Once a Princess, and Twice a Prince–this romantic fantasy has been revised and published as one book. It is set in the same world as Crown Duel, to which Sasha’s mother, Sun, was once swept away by a real prince.But not to happily ever after. Her prince vanished, and a wicked king took the throne. Since then, Sasha and Sun have been hiding on Earth, both training in martial arts until Sasha is tricked into going back to Khanerenth. She’s more than ready to kick some bad-guy butt, but is the stylish pirate Zathdar the bad guy? Or artistic, dreamy Prince Jehan, son of the wicked king? Meanwhile Sun is determined to cross worlds to save her daughter. She might not have been a very good princess, but nobody messes with Mom!
