Here may be spoilers...depends on your definition of spoilers:
Before I begin...we do have humidity in El Paso, Texas. While not a severe as the humidity in Houston or San Antonio, we do have humid weather after our summer rains. I've lived in ELP for most of my life and WE HAVE HUMIDITY!
Right...so, "The Regulators" is a wonderful sequel to Michael Clary's "El Paso Under Attack." We meet our old friends and meet new friends and foes. The format to this book is identical to the first book: we are told the story in fragments, by the protagonists (sadly, no Ivana this time).
El Paso is still under siege by the zombies, but the people of El Paso have a new foe to contend with: vampires. Enter the Regulators (led by the darling Jax and his wandering band of merry men) who aim to help the remaining survivors and destroy the new evil threatening the existence of our lovely town.
As in "EPUA," Clary does a wonderful job of not simply writing the run-of-the-mill vampires. Thankfully, these vampires don't glow. Clary's vampires are thinking, feeling villains. I could not help but love one of the vampires whom I call the "Vampire Princess." I admit I was a little wary of the way the zombies and vampires were going to co-exist, but Clary does well to have the two sets of monsters work on the page.
There are a few more plots twists in this book (when compared to "EPUA") and the book is quite gruesome on some parts. I will admit I threatened to beat the ever loving Hell out of Mr. Clary when I got to a particularly frightening part in the book. However, overall, I found this book to be quite enjoyable and liked it a bit more than the original.
