The New All-too-True-Blue History of the American Southwest - Blackbird Crow Raven - Bog

Formerly only available as volumes of the individual States, this (Southwest) anthology is one of five (West, Midwest, Northeast, and Southeast are the four others) that combine alternative (wacky/zany) histories of the States of each region, in this case Arizona, New Mexico, Oklahoma, and Texas. Each anthology also contains, as a bonus, the alternative history of the "Ewe-Knighted States" as a whole.
