From the Publishers Marketplace announcement:
Kristin Ostby at Simon & Schuster Books for Young Readers has pre-empted North American rights for Robin Stevens’s debut, MURDER MOST UNLADYLIKE: A Wells and Wong Mystery, set in 1930s England and pitched as a middle-grade Agatha Christie, featuring Hazel Wong and her best friend Daisy Wells, who find a body in their boarding school and set about investigating the murder. Publication is scheduled for spring 2015. Gemma Cooper at The Bent Agency brokered the deal.
Yes, Daisy and Hazel are coming to America! The lovely people at Simon & Schuster Books for Young Readers will be publishing MURDER MOST UNLADYLIKE in Spring 2015, and its two sequels in 2016 and 2017 respectively.
Words just can't express how delighted I am to not only have an American publisher, but one as incredible as S&S. I'm so excited to be working with the S&S team and Kristin, and I can already tell that they're going to do a amazing job of bringing Daisy and Hazel to a bookstore near you (if you happen to live in the USA).
I'll bring you more news when I have it, but for now, while everything's still sinking in - hooray.
