Schoolmarm Emma McCully needs to save her brother from being hanged for horse thieving! Thank heavens Will Lockhart, her brother's childhood friend, showed up on her doorstep, volunteering to help.
But Will is big trouble, too. He's set her heart afflutter. Worse, he's plumb loco. He calls himself an "astrophysicist." He totes around a gizmo called a "pocket computer." And, he claims tht when he moved away as a child, he traveled more than a hundred years into the future, where he's been living ever since.
