Bookouture lands multi-million-copy bestseller Mary Stone

Associate Publisher Jennifer Hunt acquired World All Language rights in eBook, paperback and audio, plus film and TV rights for two psychological thrillers from Mary Stone.

Mary Stone has sold ten million copies of her novels worldwide, across more than sixteen mystery series, and has a huge following in Kindle Unlimited.

The first psychological thriller will publish in September 2026 with traditional print distribution to follow in Spring 2027, with Bookouture in the UK and Grand Central Publishing in the US.

Jennifer Hunt said,

‘I’ve been in awe of Mary’s writing and publishing for years, and this partnership is a dream come true. Mary’s first psychological thriller with Bookouture is going to be a knock-out – with her signature deliciously dark twists, whip-smart strong female protagonists and layers of emotion and complexity. I cannot wait to get it into the hands of readers across the world, in partnership with GCP, and grow her already huge, loyal fanbase into something even more extraordinary.’

Mary Stone said,

‘I’m incredibly grateful to the readers who have embraced my stories over the years, and I don’t take that trust lightly. Bookouture has an incredible track record of championing bold, addictive thrillers, and I couldn’t be more excited to work with a team that truly understands this genre. These books explore the darker edges of trust, identity, and obsession, and I’m excited to bring them to readers worldwide with a publisher so passionate about the stories they tell.’
