Brothers in Blood — D.C. Brod

Jubal and Brig Tanner are brothers who have been feuding for years. When Brig's young girlfriend is killed, most figure the bullet was meant for Brig and the shooter was Jubal. Jubal hires a very reluctant Quint McCauley, who finds himself mired in the horse-breeding industry as he delves into the Tanner family's darkest secrets.
