USA Today bestselling Author

Welcome
to my website
Iām the author of seven psychological thrillers, published by HQ/Harpercollins . My books have all been Kindle bestsellers in the United Kingdom, the United States, Canada and Australia. The Guilty Mother was a USA TODAY bestseller and The Silent Friend was a Karin Slaughter Killer Reads pick for ASDA. The Couple at Causeway Cottage won the International Thriller Writers award for the best ebook original novel 2023.
My plots are based on ordinary people who find themselves in extraordinary ā and terrifying ā situations. I like to explore the themes of secrets and lies, jealousy and revenge. I also tackle darker subjects such as twisted love, obsession, manipulation and abuse. I try to create strong, relatable main characters that readers will root for despite their flaws.
