Meddler's Moon

What if your future grandson showed up to explain why you absolutely must marry a woman you've never met? Peter Hedgerly, a physicist minding his own business, gets exactly this dilemma when Joseph arrives from the future with urgent family business: Peter is destined to marry Marie Baker, and Joseph's very existence depends on it. There's just one problem: Peter is already head over heels for Joan Willson. What follows is a charming, witty battle between temporal inevitability and stubborn human free will. George O. Smith, writing in 1947's golden age of science fiction, crafts a premise so delightful it barely needs the spaceships. This is time travel as romantic comedy, where the universe's plans keep colliding with one man's refusal to read the script. The comedy lands beautifully, and the ending offers a twist that proves life's best moments arrive when we stop trying to engineer fate.
