Rules of Engagement

Rebecca Virtue has lost everything. Her family and friends are gone. Betrayed by someone she once trusted. Now, she is the last demon hunter.

With nothing left in Chicago, she heads to Detroit with a reckless plan-summon and destroy the Four Horsemen, starting with War. But War does not wait to be challenged. Nowhere is safe as he stalks her mind and sows discord in her heart.

Lost in the chaos of battle, Rebecca struggles to control her growing powers. With a friend's life on the line, she pushes forward blindly, willing to pay any price to see her mission through. But with her heart breaking and emotions in disarray, things only grow more complicated when she starts breaking the Rules of Engagement.
