I Woke Up In a Field, Naked, and Have to Survive a World of Monsters and Magic to Go Home

pretty much the title but

A man wakes up in the middle of a field, naked, as the title says, and has to survive a world of monsters and magic with no knowledge of this new world. He finds a notebook with a guide to this new world and a hint as to who might've sent him there and how to find them. Will he be able to get back home?
