Writer J. M. McDermott, who was nominated for the Crawford award for his debut novel
Last Dragon, is currently offering two of his more recent books for free for the next couple of days.
The offer is direct from the writer, details at:
http://jmmcdermott.livejournal.com/58888.html
Follow the instructions there and he'll email the books to you, namely
Never Knew Another, sent as both author-corrected ARC pdf and epub
and its sequel
When We Were Executioners, send as an author-corrected ARC pdf
I linked to the books above on Amazon only so people could read the synopses and reviews there. They are not free on Amazon, only direct from the writer.
While I haven't read these, I did read
Last Dragon back in 2009 and found it to be one of the more original fantasies I'd read in years.
