“The Ridge,” by Peter Eichstaedt (Sunstone Press) “The Ridge,” by Peter Eichstaedt (Sunstone Press) Nearly 60 years ago, Reies Tijerina launched a raid on the Tierra Amarilla, N.M., courthouse that led to a mini-revolution over Hispanic land grants. Peter Eichstaedt’s “The Ridge” is a contemporary novel of a fight between local Tierra Amarilla land-rights activists and the government that is eerily reminiscent of that 1967 uprising. Luke Jackman, a Santa Fe reporter, is writing about a group of Hispanic sheepherders when the group suddenly occupies a land-grant-turned-wilderness area run for the benefit of rich elk hunters. Luke is swept up in the coverage, reporting for his newspaper while at the same time acting as unwilling go-between for the revolutionaries and the police.
