There was trouble in Haven, Arizona, and Ranger Sam O'Ballivan was determined to sort it all out. Badge and gun hidden, he arrived posing as the new schoolteacher, and his first order of business was to bring the rough ranchers' children under control. To that end, he called on Maddie Chancelor, the local postmistress, whose younger brother was in firm need of discipline.

Sam wasn't sure what to expect - but it was definitely not this graceful woman whose prim, proper stance was so at odds with the fire in her eyes. Working undercover to capture a dangerous band of rustlers and train robbers was a job that had always kept him apart from other people. He was a man with his heart firmly in check - until Maddie. Now she was unwittingly tempting him down a path he swore he'd never travel.
