Helm of Darkness

Her name is Penelope C. Jackson. She is the daughter of Annabeth Chase and Percy Jackson. (Yup, they eventually got married and had Andrea. Now, they live in the merged camps of Camp Half-Blood and Camp Jupiter.)

She got her mother's beautiful grey eyes. Her father's ability to control water. Her mother's wit and her father's leadership. Basically, she got both sides of Poseidon and Athena. You may say this, "Lucky gal!" But actually twice monsters chase her, unless she is in the camps. So her life is way worse than you think.

She teams up with Cyril M. Grace (the son of Jason Grace and Piper McLain) and Andrew L. Zhang (Yup, the son of Frank Zhang and Hazel Levesque).

What happens when these three monster magnets team up?
