The Frugal Wizard’s Guide to Survival in Medieval England – description and cover

A standalone story that combines Jason Bourne, epic fantasy and time travel in which an amnesiac wizard’s only chance to survive in medieval England is to regain his memories.
A man finds himself in medieval England. He doesn’t remember who he is, where he’s from or why he’s here. He is pursued by a group of people from his own time, and his only hope of survival is to regain his memories, find allies among the locals, and perhaps even trust their superstitions. His only ‘real world’ help should be a guidebook called The Frugal Wizard’s Guide to Survival in Medieval England, but his copy blew up on the way. The few surviving fragments have given him some clues to his situation, but will he be able to understand them quickly enough to survive?
