Battle Cry of Freedom 

A Union Army captain is tasked with finding a turncoat before more blood is spilled—both on and off the battlefield—in this vivid historical mystery.   Tennessee, Autumn 1863: The Confederate Army, after being defeated at Vicksburg, has rallied to a victory at Chickamauga. General Grant is on his way to aid the besieged Northern forces—but a highly placed spy is getting in the way of that mission.   One officer has already been murdered to protect the traitor’s identity, and if the spy isn’t rooted out soon it may be the end for the Army of the Ohio. Grant recruits Cpt. Alphonso Clay for the job, but Clay’s work is complicated by a woman with her own nefarious agenda—and a little-known secret society . . .   “I can’t wait to read the next Alphonso Clay book.” —RP Dahlke, author of the Dead Red Mysteries
