Moonbow: When Realms Collide

Things haven’t been going very well for ten year old James. It seems that his normally tight-knit family is falling apart and he’s getting into trouble at school too.
When a mysterious moonbow appears in James’s garden one night, it opens a portal and he accidentally crosses the threshold into a parallel fairy realm where he uncovers a sinister plot to steal his little sister. Can James save her before it’s too late, or are they destined to remain imprisoned there for ever?
