Unhinged Cain

Cain selects his victims by the rare color of their eyes, and Kirby's unusual purple eyes make her impossible for him to leave alone. As his careful rules start bending around his growing obsession, the fallout threatens the one relationship that's anchored Cain since childhood: his bond with his twin brother Abel. Underneath her seemingly meek exterior, Kirby is a woman controlled by an overbearing mother and a boyfriend edging toward abuse — someone whose life Cain's fixation might upend for better or far worse.

Brooklyn Cross opens the Buchanan Brothers duet with a dark psychological romance thriller tracing Cain and Abel's twisted bond from childhood into adulthood.
