From the author of the Two Thousand Grueling Miles series comes Callihan, A YA Western Adventure of Revenge and Redemption.

Conn Donahey was ready to carve out a life worth fighting for. But in a single night, it all went up in flames. His new wife-gone. His hard-earned fortune-stolen. Everything he loved-turned to dust. Now, only one thing drives him forward: hunting down the nine ruthless men who shattered his life.

But this mission isn't for the faint of heart. Every mile Conn rides, every outlaw he faces, pushes him closer to a deadly edge, testing whether he's tough enough to see it through. As he rides deeper into the harsh valley known as the "Valley of Skulls," Conn has to decide-how much of himself is he willing to sacrifice for justice?

Will Conn stop at nothing to avenge his loved ones? Or will the valley claim another lost soul?
