Though a bit slow to start, once the gears start whirring in Van Essler's cross-genre lovely monstrosity of a novel, they don't stop. Thrilling, fascinating, and surprisingly fun, this story of a world ravaged by both ash-laden skies and a horrifying dementia and the heiress seeking to discover the government's dark secrets, and the cause of said dementia has every thing one could want from this kind of story. A likable, multi-faceted protagonist, a dastardly, memorable villain, even a cadre of lovable side kicks (and a cute mascot to boot!) Of course, don't take this for your usual fantasy fair, for at its heart this is pitch black, with horrific nightmare circuses and asylums full of horrifying cyborg patients, giving the novel a unique edge that keeps it from straying too far into well-worn tropes. It's the perfect combination of the thrills and frights, and should be a nice down-the-middle choice for both fantasy/steampunk and horror/mystery fans.
