The latest world to be introduced in the Wayward Children series is the Hooflands, a place filled with centaurs, unicorns, kelpies and other equine creatures that are sure to appeal to any person who has gone through a horse phase, or is still enamored with the species. 

Regan, a young intersex girl, takes off on her own one day after a horrible event at school only to find herself walking through a door to the Hooflands. There, she is taken in by a group of Centaurs who care for her until she is to be sent before the Queen to fulfill her destiny as hero, like many other humans before her have. But the longer she is there, the more Regan feels she has found a true family and isn't sure whether she wants to be the Hooflands hero or not since every hero either dies or disappears.
