Updated March 16th 2020, They are no longer open to direct submissions.
John Blake Books has been publishing bestselling books since 1991. They focus on non-fiction, particularly on mass-market autobiographies/memoirs. They also have a music imprint, a children’s Dinosaur imprint and an imprint dedicated to history, art, humor and gift books.
They are a British publisher and an imprint of Bonnier that is open to direct submissions via email.
Currently their website is under construction, which is a little frustrating. With a smaller, less established publisher this would be a concern. It is not with an established imprint of this size.
All submissions are accepted via email. Include a cover letter, synopsis and no more than three sample chapters. It’s important to note that they only respond to submissions that they are interested in. If you have not heard from them in two months, assume rejection.
