Dinosaur Knights

The opening in the forest before them was an eerie jumble of shapes and shadows . . . Roland and Oswald scanned the shadows of the clearing, constantly finding imaginary monsters in the bulky bushes and aching tree limbs. Then they saw a real one. Somewhere in the future a scientist is conducting the experiment of his life - stretching time to bring a living dinosaur to the present. But the giant prehistoric beast is stranded in the Middle Ages. There, a boy desperate to be a knight and his unwilling brother must face their fear and do battle.
