I'm now taking reprint submissions for The Mammoth Book of Kaiju, to be published by Constable & Robinson in the UK and Running Press in the US in 2016. Stories from 2,000 to 20,000 words can be emailed at prime@prime-books.com. The deadline is May 4th, 2015. (This Monday! I only have a few slots left, unexpectedly, and that's why I have a short deadline.) You will be notified soon after the deadline if your work is accepted or rejected.
Please spread the word.
