"The Island of the Nine Whirlpools" (featuring a princess and her true love, Nigel, who find the way -- via love and mathematics -- to free her from the curse her wicked father wished upon her), and "The Last of the Dragons" (about a princess who, not wanting to uphold the tradition that all royal maidens must be rescued from the dragon by their prince, insists that she be allowed to fight the dragon herself -- only to discover that this particular dragon is not at all interested in eating Princesses . . . nor in being killed by one).
