HEAD OF ZEUS
HoZ won independent publisher of the year 2017, and it’s easy to see why. They publish genre fiction, children’s books and narrative non-fiction, including authors such as C. J. Box and Graham Masterton. They do accept unsolicited submissions via a submissions portal, but when it gets very busy they temporarily close. Check by periodically. Keep in mind it can take many months to get a reply. I waited six. This is their current website: http://headofzeus.com/ but they will be updating it shortly to this: https://uat.headofzeus.com/home?_ga=2.135399476.466581387.1566109317-1495559976.1561452066
One of the UK’s leading independent publishers of crime, thriller and mystery fiction, Joffe Books publishes Helen H. Durrant, Joy Ellis and Faith Martin amongst others. They accept submissions from unagented authors – even if you’ve self published your book (a lot of publishers don’t).

Best of luck with your submissions! As a thriller writer myself, I know what a daunting, frustrating, infuriating task submitting to publishers and agents is.

Why not check out my proofreading services? £40 for a proofread of your cover letter, synopsis and first 10,000 words of your MS.
