Sunnie Begay's only mission in life is to kill the leader of the Skinwalkers, the Navajo Wolf, after she was duped into helping them. Instead, she accidentally shoots bounty hunter Francisco "Cisco" Santiago, who's on the reservation to look into the cold case of his father, who died under mysterious circumstances. Sunnie, who feels she's living in a gray world, and Cisco, who thinks he knows nothing about love, find life more colorful when they are together. Will they be able to overcome their painful pasts to realize that love is all that really matters? With Shadow Whispers (4), Linda Conrad brings one of the overarching stories of the beautifully conceived Night Guardians series to an end. Hopefully another trip to this magical and mystical world is not too far off!
