Percy Jackson's Twin *ON HIATUS*

There is a secret that nobody at Camp knows. Percy had a twin sister named Cassiopeia that was killed when they were 12. What happens when people start to suspect? And what are their reactions to finding out about her?

These are going to be one-shots about Percy, Cassiopeia, and Co. There will be a lot with 2-3 parts cause they get too long. I take suggestions and requests for these and if the title had an A on it it means alive. It'll make more sense if you read. Enjoy!!
