Pandora's Box by Gracen Miller

Where does the road to Hell begin?

What happens when your son turns homicidal overnight and your husband disappears on his way to work? Do you cower in fear or fight for your life? Madison Wescott fights against the odds. Distrustful of a God she doesn't believe in, she finds herself face-to-face with a world she didn't know existed and discovers her own soul is darkened with demonic connections.

With good intentions? Or by demonic design?

Phoenix Birmingham bursts into Madison’s life in a whirlwind of sarcasm and sexual appeal. A hero for the masses—and for her jaded heart—but few will ever know the sacrifices he has made or the sacrifices to come. Discovering her entire life has been influenced by multifaceted paranormal beings, Madison is determined to defeat the apocalyptic blueprint fate has decreed, but only one man dares to challenge the supernatural forces manipulating them. Even with Phoenix's aid, can destiny be denied? Or will demonic design prevail while they pay the crucial price with their souls?

In a small, sleepy Alabama town the battle for mankind's liberty has begun...

My review:

Holy shit! Are you a fan of Laurell K. Hamilton or Sherrilyn Kenyon? Then you'll love Gracen Miller. Pandora's Box blew me away. I started reading it after supper, read most of the night, and in the morning, when I woke up, I stayed in bed and read until I finished. There was not one moment where I felt the need to skip over lines to get to a more exciting part. 
In the first book in the Road to Hell series, Gracen takes us on a phenomenal ride. Whether its fighting demons or hunting down one of the many evils we don't know exists in this world, this story never slows down. Add in fantastic characters that you can relate to, situations that take you on an emotional roller coaster, then add a twist makes you want to scream and this book is one I completely fell in love with.
And the end? Oh, my god! I wanted to scream. Hell, I wanted to go to Hell so I could.... ah, damn it. I can't break my no spoiler code, now can I... 
If you're a fan of paranormal and like your stories with some adult flair, this is a book you'll want to pick up. And when you're done, I guarantee you'll be going to buy Hell's Phoenix, the next book in the series.
