Eidolon

As Edward Walker comes to grasp more about the strange world around him, he begins to suspect that his family has guarded a secret for a thousand years. The Other and the creatures called Eidolons are also keeping secrets that bend the mind.

Edward must work out whether he can find the key to his future, and whether his mind can bear what his past holds. The stakes reach beyond him: unless the truth comes to light, nobody may have a future at all.
