In the early 1970s, Ethel Grady Lane returns to her hometown of Sweetheart, Arizona with one thing on her mind: killing the man who murdered her family. But first, she''ll have to find him. As Ethel navigates the eccentric town and its inhabitants, she learns that the quaint veneer hides a brewing darkness. She has no choice but to descend into a ring of depravity and violence, with her only ally an Old West novel that follows famed gunslinger Solomon Eaton. As both stories unfold simultaneously, a love of fiction informs choices in reality, for better or worse.
