The Demonic Inventions of Aurelie Blake by Mara Rutherford (April 14, HarperCollins, Hardcover)
In Wisteria, the very act of innovation is forbidden. Any creation—art, music, engineering—conjures a demon from the other side. The greater the innovation, the more dangerous the demon.
This has never stopped Aurelie from inventing—but it has made it more difficult. Her inventions are small by necessity, producing demons that she is capable of dispatching alone. But she knows she’s meant for something greater, and each day has her chafing more at the boundaries of her society.
Destrier lost his parents to demons as a child, and has devoted his life to preventing more senseless murder at the hands of demons. He was young when he joined the hunters, and each year he’s grown stronger. But it’s never enough.
When a mysterious figure offers Aurelie a job she can’t refuse—an impossible, magnificent invention—her decision to accept sets off a chain of events that will alter every aspect of their world… and sparks the connection that will change both Aurelie and Des irrevocably.
