Now or never

A long, long time ago... The Gods in Olympus created an island and filled it with their greatest warriors from all over the world. Greeks, romans, english, irish, spanish, ext. They surrounded the island with a magical barrier, in the form of a triangle, so none could leave or enter. That is... until now. THe island of Stroid is located in the middle of a place you might know as The bermuda Triangle. Though to us it is known by The Sea Of Monsters.

There was a boy who'd just turned 15. He's family was poor and served the royals on the island. He'd been bullied at school since he was little,they called him jitterumb(jittery and dumb), He could never read any thing since he had dyslexia and was always jumpy thanks to his stupid HDHD.  Little did he know that he's work at the palace would take a wrong turn. Su nombre es Diomedes.(He's name is Diomedes)

There was girl. Whom had just turned 14. Her sister had once married a prince and died later on, with the sweating sickness. She was now alone with no one but her mother to turn to. Her dad had died when she was little. Her mom is a demigod, daughter of Aphrodite and his dad son of Hephaestus. She was suposed to take the throne as the king and queens daughter, since no one knew she wasn't royal blooded, their plan was working fine. But then her mom fell ill aswell with cancer. Daria didn't want the throne anyone and was misjudged and forced to continue to plan. That is untill a handsome boy named Diomedes caught her atention. Her powers, which she inherited from both parents is now at risk. Will everyone find out about her secrets?

I wouldn't call them demigods. They are the children OF the demigods.
