Raaahhh! Night is falling . . . playtime is nearly over . . . and bedtime is looming. But brave King Jack is more than a match for dragons and terrible beasties! With a band of faithful knights and a mighty castle too, this magical, make-believe adventure is just perfect for little boys and brave children. Jack, Zack, and Caspar build a castle fort, then spend a day fighting dragons and beasts, but at day's end giants carry away first Sir Zack, then Caspar, and King Jack is left to face night creatures alone.
