CAT Latest of Zack Tolliver, FBI Series (#4)
(Published 2016) "She paused, waited. It came again, far beyond the pasture fence, up the wooded slope toward the higher elevations; a call of some creature, a wolf, coyote, maybe an owl, she couldn't tell. It didn't come a third time."

Zack Tolliver, FBI, rushes home to Tuba City, Arizona, after he learns his friend Eagle Feather was involved in a hunting accident––a mountain lion attack. The Navajo hunting guide's client is seriously injured. Zack knows the only way to cure his friend's guilt is to hunt the cat down. But he quickly learns this is no ordinary cat, and this will be no ordinary hunt.

ZACA Zack Tolliver FBI Series (#3)
(Published 2015) "The sun was almost gone behind the ridge. The strange bends in the oak branches and shadows in the dense chaparal, cloaked in dusk, took on new meaning. It was dead quiet. Zack felt the hair on the back of his neck prickle."

A farm worker disappears, another takes his place, the numbers stay the same. Rancher Rufus Reyes isn't fooled. His operation is small, he knows everyone. Then another worker disappears and no one takes his place. The man's wife is hysterical, yet won't talk. Reyes needs help.

In this third book of the Zack Tolliver, FBI, series, Dr. Susan Apgar asks Zack to help her deliver a lecture to a college criminal justice class. A pleasant junket to California's beautiful Central Coast, thinks Zack, but instead he becomes immersed in a case involving drug smuggling, rival cartels, murder, and an old enemy. The clues begin to add up, the victims pile up, the mystery grows ever deeper, and the danger more imminent.
