A guest asked me to recommend some good books about Texas ghosts, so I thought I would add some here.
To be honest, there aren't a ton of really great books that I have found... The best ghost stories are the ones that are fiction, and usually reporting of ghosts is sketchy at best.
However, Dayne and I used a few books to help guide us on our ghost-hunting vacations...
Haunted Texas Vacations, Lisa Farwell. This is where we learned all about Jefferson, TX, the most haunted small town in Texas. We love that place, and not just for the ghosts - it is truly a charming area up in East Texas. Farwell's stories are in the first-person, telling of her own experiences, kind of like what we do on our ghost tour.
When we were in Jefferson, we met Michel Whitington, who owns the most haunted house in Jefferson (formerly The Grove Restaurant). He also writes books about his experiences with ghosts and stories from around Texas. He has a whole series of them, and the best (in my opinion) is Ghosts of East Texas. Learn more about The Grove, Mitchel, and see his books here: http://thegrove-jefferson.com/.
You can find these books on Amazon.com or even at Half Price Books, probably.
