Waking Dream (HB) by Rhiannon Lassiter
On a table lie three books, each with a name on the front. Bethany, Poppy and Rivalaun. Bethany's father has just died, and he's left her a mysterious painting. Poppy is her cousin - who thinks she's a witch. And Rivalaun has travelled from another world to be here - and only he knows what the secret of the three books is. Through their dream diaries, the cousins' worlds intersect - until it begins to seem that their dreams are more real than anything else...In an astonishingly dark and powerful story, magic and reality interweave to produce a heart-stopping, sometimes terrifying glimpse of another world - is it death, or dream?
