Also known as Holly Cassidy (romantic comedies)

I was born in the UK grew up in Switzerland, and moved to Canada in 2010. Unsurprisingly I love chocolate, mountains and cheese, and books, of course.

My first novel, TIME AFTER TIME, a light-hearted romantic read, published in 2016, after which I moved to the dark side.

My internationally bestselling thrillers include: THE NEIGHBORS (2018), HER SECRET SON (2019), SISTER DEAR (2020), YOU WILL REMEMBER ME (2021), NEVER COMING HOME (2022), THE REVENGE LIST (2023), ONLY ONE SURVIVES (2024), and A KILLER MOTIVE (2025).

I also returned to my romantic comedy roots with THE CHRISTMAS WAGER, written under the pseudonym Holly Cassidy (2023) and THE CHRISTMAS COUNTDOWN (2024).

I'm now working on a new novel.
