Emerald Isle of Mists

Prince Argon has taken Lady Kersta and her companions hostage because he needs them to help him rescue his sister from captivity and then he must return to his princedom and make his twin brother pay for his crimes. Kersta and her friends have special abilities that he hopes to use. But now they have a new problem. The prince's sister is being offered to either one of two suitors, and they're in the fight to the death to keep her. The man who holds the strings is a king who claims she's his niece, but Argon knows the man is not their uncle! 

Kersta can't believe she and her companions have paid passage on the prince's ship to take them home and instead he's taken them to the Emerald Isle of Mists on a rescue mission and all because a soothsayer has predicted this will come to pass. Not only is danger all around them, but Kersta's whole life is about to be turned upside down.
