In Larry McMurtry's "Sin Killer, " the first novel of a major four-volume work, it is 1830, and the Berrybender family, rich aristocratic English, and fiercely out of place, is on its way up the Missouri River to see the American West as it begins to open up. At the core of the book is daughter Tasmin's relationship with Jim Snow, frontiersman, ferocious Indian fighter, and part-time preacher (known up and down the Missouri as the "Sin Killer"), the strong, handsome, silent Westerner who captures her heart. Larry McMurtry has created a wonderfully engaging family confronting every bigger-than-life personality of the frontier as the Berrybenders make their way up the great river, surviving attacks, discomfort, savage weather, and natural disaster. At once epic, comic, and as big as the West itself, it is the kind of novel that only Larry McMurtry can write.
