A young couple, a friendly beachcomber, lots of bullets and plenty of death.         It all starts innocently enough with Carrie and her new boyfriend driving her father's RV to south Texas. When they get stuck in the sand on Boca Chica beach, Leo, a seemingly easy-going local, comes to their rescue and pulls them out.        But after midnight, a wounded and far more intense Leo returns, now hunted by killers. Gun in hand, he forces the couple to help him escape. Once they're back on the road, the danger--and number of enemies--grows.        Leo and Carrie, tightly held In the Lion's Mouth, face a harrowing gauntlet of secrets stretching from Texas to the streets of Matamoros. A fast-paced thriller with colorful characters from both sides of the border.        Written by the winner of Oklahoma's 2013 Book of the Year in Fiction.
