I've just joined The Red Dragon Inn and have been reading this thread based on my book with interest.
I'm the author of 'Robin Hood and Friar Tuck: Zombie Killers - A Canterbury Tale by Paul A. Freeman'. I emailed Almeric a few days ago, and thought you might be keen to hear some background on my particular book.
When Coscom Entertainment (an independent horror publishing house) asked for submissions for a book of zombie poetry (yes, seriously!), I submitted a narrative poem of 1,100 words. The editor liked it and said if I could write a similar, 18,000-word narrative poem, he would publish it as a stand alone novella.
Since I write Canterbury Tales in the style of Chaucer in my spare time, I decided to write one including zombies. But who would fight this menace? The major 'superhero' of the English medieval age being Robin Hood, I decided to take the characters associated with the Robin Hood legends and incorporate them in a book.
The title of my book was problematic. Originally titled 'The Monk's Second Tale' (because it's the second story told by Chaucer's monk character), I needed something a bit more eye-catching - hence 'Robin Hood and Friar Tuck: Zombie Killers'.
One aim of the book is to introduce readers to a more accessible form of the Chaucerian style of poetry (iambic pentameters, rhyming couplets, etc, etc), hopefully to encourage students of English literature to move on to Chaucer with confidence rather than trepidation.
Anyhow, thanks for giving me the opportunity to elucidate on what probably sounds like a quirky book and good luck with your freeform story based on the title.
Below is a link to the RH&FT publisher's page, and my rather rudimentary website which explains in more detail my Canterbury Tales project:
