Hi, wanted to mention this book before I pass it on to my DD. It's historical fiction, meticulously researched. I really enjoyed it and learned about the Mexican side of the Texan war for independence, not to mention new information about the whole Alamo story. The protagonists are so real I thought they were for a good portion of the book!
"The Gates of the Alamo" by Stephen Harrigan
Harrigan has also written "Aransas" and "Jacob's Well", neither of which I can find at my local used book store.
