Carnival of Monsters by S.J. Sanders

The Ravening had left the world destroyed and more than one life irrevocably changed. For MaryAnne, who survived for years alone out in the destruction through the rise of new surroundings and creatures sharing their world, The Children’s Home has been her personal sanctuary, giving her peace and purpose.

But new nightmares walk their world. Nightmares that whisk away the children in the wake of a fae carnival. Determined to find the lost children, MaryAnne is forced to confront her fears as she strikes out to find The Night Carnival and whatever answers it may have for what she seeks. Drawn by an explicable pull to a troll who haunts her, she is to discover that not everything is at it seems. The Night Carnival, which promises the extraordinary and moments of rare pleasure to those who attend, possesses an inescapable danger for fae and humans alike. And the troll who awakens her blood and chases her fear away may be the biggest danger… to her heart. If they even survive. Because the darkness of the carnival hungers for something and the strange fog cries out with the voices of children as the Hallow Night draws near.
