Michael G. R. Tolkien - Wish

Tolkien, who has published six collections of poetry, was forced to self-publish Wish through Authorhouse after publishers turned the book down.
"My agent tried with admirable persistence and tact every cast of possibly appropriate publisher both here in the UK and in the USA, and it received plenty of favourable comments; but apparently the sticking point was simply a puzzlement as to what shelf it would sit on to sell," http://www.guardian.co.uk/books/2010/aug/11/tolkien-dickens-descendants-collaborate
