Thomas Rimor last battled elven knights, but now that ancient evil has returned. Thomas must take on a new identity to fight both human and elven foes: that of Robin Hood.

It's been nearly a century since Thomas Rimor last battled Yvag knights. In that time his wife and daughter have grown old and died, and he has discovered that he ages not at all. The elven world believes him long dead.

In his grief, he has retreated to the depths of Sherwood and Barnsdale Forests and become a hermit, lost in his memories, his grief. But when a dying outlaw arrives on his doorstep with items stolen from an Yvag skinwalker, it sets in motion events that thrust Thomas back into the world and force him into combat with Queen Nicnevin's soldiers once again, including this time his late sister's changeling daughter and the Queen's own grotesque offspring, Bragrender.

As Thomas takes on two sheriffs of Nottingham and a horde of Yvag raiders, he enlists the aid of outlaws Little John and Will Scathelocke, and the Keeper of Sherwood Forest herself, Isabella Birkin, who sets him on a path back to humanity. To keep his true identity hidden from the Yvags, he creates an alter-ego named Robyn Hoode, whose exploits, unbeknown to Thomas, are about to become the stuff of legend.
