Elizabeth Conway's greatest ambition is to discover a comet. Unfortunately, she is the eldest of eight daughters of an earl, so her relative expect her to take her rightful place in Society. The heavenly bodies she views through her telescope hold far more fascination for Elizabeth than any mere male, although her perpetual beau, dashing Lord Bevis, would change that if he could. When Tom Conroy, a distant cousin and the new Earl of Clanross, appears after a year's delay, Elizabeth offers him a cool welcome. He is a dull stick and ill-mannered to boot. Yet he is the only man who has shown respect for her astronomical work, and his concern for her younger sisters' welfare reveals a different side to him. Then his heir, Elizabeth's cousin Willoughby, appears with the obvious intent of making a match between his lovely but silly sister and Clanross—and with making as much mischief as he can. Lord Bevis presses his suit with Lady Elizabeth, until she agrees, at long last, to marry him.
