The Banned Son

6 siblings, Ean, Lea, Richard, Rain, Teal, Parker just find out that they are halfbloods, and also that one of them isn't really their sibling. Ean and Richard get kidnapped, so the rest of the group, splits up. One half goes to camp Half-blood and the other goes to save the lost ones. Does include some PJO charecters. Feedback needed!
