Isle of View (Xanth, No. 13)

Lovelorn
Loveworn Love Lost
Perplexed Prince Dolph, Xanth's precocious shapeshifter, should be in love but isn't. Nonetheless, he must chose between two fiancées -- Nada the uninterested and Electra the uninteresting -- or all three of them will suffer the most dire consequences. Luckily a convenient catastrophe has popped up to distract Dolph form his dilemma -- the foal-napping of young Che Centaur by goblins. And the only one who knows where Che is is a nice but remarkably naive elflike gir named Jenny from the World of Two Moons. If anyone can save the missing centaur...she sure can't.
