The definitive history is "Lone Star" by T.R. Fehrenbach. It's a big, long read, so maybe not what you're looking for.
Lone Star Nation, already mentioned, is fairly good.
Probably the best short history of the revolution is "Texian Illiad" by Stephen Hardin. That's pretty common. (note:
illiad, like Homer - stupid Texags and their sans-serifs fonts)
There are a ton of good Alamo books out there. Walter Lord (who wrote an excellent Pearl Harbor book) has written a fairly good one "A Time to Stand" and Lon Tinkle's "13 Days to Glory" is good.
William Binkley's "The Texas Revolution" is not bad, and fairly short.
In terms of fiction, there's a lot out there. James A. Mitchener's "Texas" is a classic, but so is War and Peace, only War and Peace is shorter.
I found a pretty cool paperback called "Empire" by Terry Coleman, a British writer, at a kiosk in the Paris East train station. I've never seen it since. It's set in the Republic and goes into a lot of the nuances about how close Texas came to never being annexed. Being British, he plays it up a little, as that was something the British wanted, but in my other reading, that's something I think most people don't realize - how annexation and statehood was not foreordained, and how both the U.S. and Texas publics were moving
away from that position for a time, before events pulled them back. The guy takes a few liberties with his portrayal of Sam Houston, but otherwise, it's a good read. Of course, when you're stuck in Paris and it's cold and raining, any book on Texas is a good read.
There's a ton of good stuff out there, and I myself have not read as much as I would like to. However, I have built up a huge collection, and one of these days, I will go on a binge.
