Murder at the War (also known as Knightfall), by the SCA's own Mary Monica Pulver, is available from Amazon.com for FREE download August 29, 2013 only. The book is set at the Pennsic War.
“I was just thinking that the Society for Creative Anachronism is actually very much like the old Norse myth of Valhalla: You can fight all day, get killed any number of times, and still be in great shape for the feast that night!”
…until one of the fighters, Thorstane Shieldbreaker, is genuinely murdered, when the fun turns to deadly seriousness as Lord Stefan von Helle and Lady Katherine of Tretower struggle to solve the crime. Was it one of their own SCA members, a mundane outsider, or Lady Katherine herself?
