Nick Redfern and Ken Gerhard are two of my favorite authors. So, it probably wouldn't be a surprise that I have a book written by both of them - Monsters of Texas. Published by CFZ in 2010, it is all about the many cryptids that have been reported in the Lone Star State.
Recently I finally got around to reading the book, which I thoroughly enjoyed. Gerhard and Redfern discuss accounts of sightings of Bigfoot, thunderbirds, possible living dinosaurs, werewolves, goatmen, chupacabras, out-of-place animals, aquatic monsters, and much, much more.
Each chapter is written by one of the authors, with 7 by Gerhard and 5 by Redfern. Overall, it makes for a very interesting book, and one which I should have read a long time ago. If you are interested in cryptozoology, you should definitely check it out. You'll be surprised at how many monsters are said to live in Texas.
