Besides cheating and choosing a Star Trek novel, I can think of several.
Eoin Colfer's Artemis Fowl might not be a bad one. Almost no matter who I chose, I'd have a comfortable life style.
Brandon Sanderson's Mistborn would be miserable to live in, but if I was a character with allomancy, that might be acceptable.
