"When trouble strikes in Haven, Arizona, Ranger Sam O'Ballivan is determined to sort it out. Badge and gun hidden, he arrives posing as the new schoolteacher, and discovers his first task: bringing the ranchers' children under control. So he starts with a call on Maddie Chancelor, the local postmistress and older sister of a boy in need of discipline. But far from the spinster Sam expects, Maddie turns out to be a graceful woman whose prim and proper demeanor is belied by the fire in her eyes.

But something about the spirited postmistress tempts him to start down a path he swore he'd never travel. "-- P. [4] of cover.
