Step through the door to Lost Pages and escape a life you never wanted...On her tenth birthday, Aydee runs away from home and from her neglectful parents. At first, surviving alone on the streets is harsh, but a series of frightening, bewildering encounters with strange primordial creatures leads her to a bookshop called Lost Pages, where she steps into a fantastic, sometimes dangerous, but exciting life. Aydee grows up at the reality-hopping Lost Pages, which seems to attract a clientele that is either eccentric or desperate. She is repeatedly drawn into an eternal war between enigmatic gods and monsters, until the day she is confronted by her worst nightmare: herself.
