When I was young, I was always told that everyone loved a tragic Greek love story. Orpheus and Eurydice. Apollo and Hyacinth. Hero and Leander. Achilles and Patroclus. I had asked my mother why so many of those stories didn't have happy endings. She just gave me a grim smile and told me how the world of the gods was tricky. There was a lot about it that I didn't understand yet. That was 13 years ago. I think I understand it now. Cass Paige was the only child of Poseidon at Camp Half-Blood. Having come to camp at such a young age and being a child of the Big Three, most campers left her on her own. That was, until Annabeth and Luke. She befriends the two and finds something she never knew she needed. Then came the arrival of Percy Jackson. And everything changed.
