If the original had sold there would have been a sequel.
Four years ago, I started to write the sequel to my story A Sailor's Love - www.draft2digital.com/book/34522 ; and then put the concept on hold. The reason is the first story has not sold in all this time.
If there were some sales for the romance about a young lady who finds her spiritual peace on the seashores, I would happily write the story as I enjoyed creating the characters, and their loves and lives.
A Sailor's Love is mildly erotic, but the story is an erotic romance, not essentially erotica.
