‘The success of the Detective Josie Quinn series continues to amaze me. I am so fortunate that even after 22 books, my readers are so wonderfully passionate about all things Josie and impatiently awaiting book 23. They are truly the best readers in the world, and it’s a privilege to write these books for them. I am absolutely ecstatic to continue to meet milestones I never dreamed possible. As always, I have the team at Bookouture to thank for their brilliant, innovative approach to publishing. Watching the series become so popular in Europe through their translation programme has been immensely exciting and gratifying.
