An investigative job offered by an old family friend sends her to a lonely corner of New Mexico, to try to free an innocent man wrongly convicted of a brutal double murder. As she pursues justice for the unfortunate prisoner, she finds herself caught up in the saga of New Dominion, a nearby town wiped out in a bloody massacre back in 1933…but is somehow rising from its own ashes. Annie’s presence creates unexpected ripples, summoning ancient, demonic forces and causing tragedy to repeat itself—unless she can find some way to stop it.  Cold Black Hearts is a riveting supernatural thriller, and Annie O’Brien is bound to be your new favorite character!
