Perfect for fans of Aru Shah and the End of Time and Amari and the Night Brothers, this sequel to Ciannon Smart’s Rayleigh Mann in the Company of Monsters takes Rayleigh and his friends on a thrilling treasure hunt through Below-London to unravel a monstrous mystery.

On the previous All Hallows' Eve, Rayleigh was just a typical Londoner. Or he thought he was.

Now Rayleigh has embraced his monster heritage, passed all the tests to stay in Below-London with the rest of monster society, and even saved his father—the Bogey Mann—from the notorious Illustrious Society.

But his adventures are far from over.

Though Rayleigh is supposed to be staying far away from trouble, it’s found him once again. As strange shadows begin to reach out to him for help and clues begin to fall into place, Rayleigh and his new friends are embroiled in a mysterious treasure hunt to prevent Below-London from falling into chaos—and not the good kind, this time.

Fans of The School for Good and Evil and Tristan Strong Punches a Hole in the Sky will thrill as they and Rayleigh return to Below-London—soaring across the city, exploring libraries that disregard the rules of space and time, and meeting new friends as they uncover a sinister plot and embark on another unforgettable adventure.
