Enchanted Glass [EPUB ebook] 

A brilliant, intricate and magical novel from the Godmother of British fantasy.When Andrew Hope’s magician grandfather dies, he leaves his house and field-of-care to his grandson who spent much of his childhood at the house. Andrew has forgotten much of this, but he remembers the very strong-minded staff and the fact that his grandfather used to put the inedibly large vegetables on the roof of the shed, where they’d have vanished in the morning. He also remembers the very colourful stained glass window in the kitchen door, which he knows it is important to protect.Into this mix comes young Aidan Cain, who turns up from the orphanage asking for safety. Exactly who he is and why he’s there is unclear, but a strong connection between the two becomes apparent.There is a mystery to be solved, and nothing is as it appears to be. But nobody can solve the mystery, until they find out exactly what it is!
