Two to the Fifth by Piers Anthony

This collection of excerpts introduces a world of magic and puns, following a cyborg named Cyrus as he undertakes a quest to see the Good Magician. Along the way, he encounters a host of unusual characters, including a sarcastic robot donkey named Don, a healing nymph, a whirlwind with a feisty personality, and various women with peculiar talents and behaviors. Cyrus is also tasked with forming a traveling troupe to perform plays, which becomes entwined with a larger mission involving a powerful being named Ragna Roc and a complex understanding of magic, relationships, and a hidden "Adult Conspiracy." The narrative includes fantastical challenges, explorations of identity, and the development of unexpected romantic connections, particularly between Cyrus and a young, powerful sorceress named Rhythm, which complicates the Adult Conspiracy rules.
