Through Roads Between — Amy Laurens

Sanctuary is a place of safety -- or so the fairies say... Edge is ready to return to a normal life, after beating back the shadows and defeating the Valley. Even Scott -- bane of her existence -- has been relatively well behaved since their encounter. But when Edge's best friend, Gem, collapses in class, Edge realises the Valley's evil shadows are back. Worse, this time they're targeting Gem. With Gem banned from Sanctuary by the fairies, the only person left to turn to is Scott, who knows firsthand what it's like to be possessed by the Valley. But convincing him to help is going to be tough. Time is against her. The fairies are unforgiving, and even if Edge succeeds, the cost may be her access to Sanctuary itself. But anything is worth it, if she can save her friend.
