Author's Publish for this week is a roundup of romance publishers (including many of Harlequin's myriad imprints) that take direct submission of manuscripts. It's a perpetually hot (in more ways than one 😉) genre and just seems to keep growing. Right now, for instance, romantasy (romance fantasy) is massive. I don't know if I have a romance novel in me, but I have certainly written stories with romance elements both for here and other sites.
