Some would call River Rydell a 'chosen one': born with the ability to see monsters and travel to a terrifying spirit world called The Otherwoods, they have all the makings of a hero. But River just calls themself unlucky. After all, it's not like anyone actually believes River can see these things-or that anyone even believes monsters exist in the first place. So the way River sees it, it's better to keep their head down and ignore anything Otherwoods related. But The Otherwoods won't be ignored any longer. When River's only friend (and crush) Avery is kidnapped and dragged into The Otherwoods by monsters, River has no choice but to confront the world they've seen only in their nightmares-but reality turns out be more horrifying than they could have ever imagined. With only their cat for protection and a wayward teen spirit as their guide, River must face the monsters of The Otherwoods and their own fears to save Avery and become the hero they were (unfortunately) destined to be.
