Shadow Shepherd
As a former political tracker with a brand-new law degree, Sam Callahan has turned his life around, leaving behind a childhood ravaged by abuse and a fatally dangerous job shadowing political candidates. Now a lawyer, Sam hopes for a risk-free future, but harm’s way has a much longer reach than he could ever expect.
His very first legal client is gunned down in a Mexico City hotel, and Sam barely dodges a bullet himself. Suddenly on everyone’s most-wanted list—brutal hit men, hostile cops, relentless FBI agents, and even an infamous assassin—he doesn’t have the luxury of finding out why.
When Sam’s girlfriend is dragged into the fray by a kidnapper, Sam would do anything to save her life. The catch? He’s got only twenty-four hours to do it…but any number of ways to die.
