On the day of the funeral Andy is shocked to discover one thing: the person in that casket is not her sister.

Violet is alive.

Convinced her sister’s elite boarding school is covering up the truth, Andy enrols at Griffith Academy to discover what really happened and find Violet.

After discovering a cryptic note from her sister, Andy must follow a set of clues to unlock the truth. This will bring her into contact with secret societies, ancient magic, demons and monsters. And a charming senior named Jae Han who has his own reasons for finding out what happened to Violet…

Soon Andy realises the price she must pay to bring her sister home is darker and more dangerous than she ever could have imagined.

ALL THE DEVILS is the first novel in the author’s Sisters of the Occult series. The second novel, ALL THE WICKED, is due to be published by Michael Joseph in the UK, on November 6th, 2026.

‘ALL THE DEVILS is eerie, intense, and mysterious with immersive world building and mythology. The fast pace kept me turning pages, and I’d follow Jae pretty much anywhere.’ — Stacia Stark, bestselling author of the Kingdom of Lies series

‘A deliciously dark and atmospheric read. I tore through this gothic tale of a sister’s love and the monsters she will face to unearth the shocking truth.’ — Frances White
