Grimm Throne by August Booth (ebook)

Every fairy tale needs a proper ending. Prince Benjamin knows in his heart that the steadfast belief in even the possibility of a happy ending in his world is indeed a powerful thing. That is why he assembles a royal army of friends and family to take them on a journey to the Emerald Castle, take down the antisemitic King of Grimm, and reclaim his royal throne from the thieves who stole it from him.
