The Whirlwind in the Thorn Tree

A two-fisted, gunpowder punk must-read.
When a famous writer is murdered, his estranged son Ross returns for the funeral and is quickly plunged into the unfamiliar community of fantasy geeks and role playing nerds. And when he learns that the fantastical world of his father’s fiction actually exists, Ross quickly crosses over to hunt the killer down, but soon realizes that he may have jumped the gun, because now he’s lost in a world of gunslingers and monsters where the rules make no sense.
And he hasn’t read the books.
