The Midnight Carousel by Fiza Saeed McLynn

920, Chicago
Maisie Marlowe has come to America for a fresh start. After discovering an antique fairground carousel, she is seized by the idea of running a glittering amusement park. But little does she know that the wondrous object has a sinister past of its own.

Paris
A decade ago, fairgoers inexplicably vanished riding an extraordinary carousel, and Detective Laurent Bisset closed the case with a suspect behind bars. So when rumors of fresh disappearances in Chicago also linked to a carousel make their way across the Atlantic, Laurent sets out for new answers to an old mystery.

Maisie and Laurent both hold clues to this dark puzzle.

But can they piece it together before the carousel claims someone else?
