Alisha Dainton has severe epilepsy, so she's used to having seizures. Sometimes she even has weird visions and hears strange noises. After a particularly bad episode on holiday in Cyprus, what she sees and hears makes her think she s going mad: who is the beautiful girl with the see-through eyes, multi-coloured hair and rainbow and the half-woman, half-bird creature singing by the hotel pool, and just why has she been chosen to go back in time to ancient Sparta to help save a princess called Helen? Either Ali is having some sort of bizarre dream, or she's about to have an amazing adventure that might change the entire story of the Trojan War.
