Death's Wishes (A PJO Fanfiction)

Okay, for one thing, it's not like a dirty fanfiction or whatever, k? It's just basically a character of mine is a demigod and meets other characters of mine yadayadayada. So, if you are looking for some dirty stuff.. Here's not the place. Although, I may add some..mature..jokes. ;)
Okay, description time.
Robin Lancaster, and her twin brother, Jace Lancaster, are each demigods. They find this out when Jace's secretly satyr friend, Jasper, tells them both and brings them to camp. They go on a mission with Jasper, Alex (a son of Hermes) to restore peace to Olympus. Will they succeed?

By the way, the original series of Percy Jackson is originally by Rick Riordon. I suggest you read it if you haven't!
