After the death of her grandfather, neurodivergent tween Ramya uncovers a world of mystery and magic—and she’s the only one who can see it! From the award-winning author of A Kind of Spark. “Ramya, you have something this city needs. And it’s something that’s going to change everything.” Ramya Knox always knew she was different. Her dyspraxia makes her clumsy and prone to attracting the disapproval of her teachers. Ramya didn't know she can see magic! But when a dog statue comes to life, Ramya follows the pup and discovers a world she thought existed only in fairy tales. Trolls, witches, kelpies, vampires, and more lurk in the shadows of Edinburgh, hiding from the most dangerous creature of all: sirens. These beautiful monsters use their persuasive voice to convince those around them to do their bidding—for better or worse. As the sirens rise in power, it's up to Ramya to save the day—or the Hidden and mortal worlds might both be at risk.
