The Riddles of Epsilon

the long version

YA. The doorstep was black, shiny as glass. Through the layer of dead leaves, I found some symbols, and in English: Where -- Silon dwells. Jess White, age 14, has been uprooted from her home and taken to live on a remote yet populated island, at the whim of her parents - Mum is an artist; Dad a photographer. While she is bemoaning her new (lack of) life to her best friend via a computer chatroom, they are interrupted by a third party - although only Jess is aware of the presence that calls itself 'V'. This is the start of a most extraordinary and creepy mystery as Jess finds herself caught up in a cycle of deadly occurrences.
