This is one of the best local histories I have read in some time. It is thorough, well researched, well written and entertaining. Focusing mainly on the Rio Grande Valley in New Mexico from Soccorro to El Paso, Kiser looks at the predominate city during this time of turmoil, Mesilla. From the take over by the Americans in 1846, through the arguments arising out of the border situation created by the Treaty of Guadalupe Hidalgo and the finality of the Gadsden Purchase, he follows interesting, all too human characters throught these years. He covers the southern invasion and tyranny of Baylor which he puts in interesting juxtaposition to Carleton as the martial law tyrant, following the Southern expulsion. Really a well done book. If you are interested in NM, the west, or the development of the US it is worth the read.
