Luck of the Draw

Summoned into Xanth as the stake in a demon's wager, an older mundane man named Bryce finds himself transplanted into a younger, magic-capable body, with the catch that he's agreed to court and marry a princess who wants nothing to do with the arrangement. Winning her over turns out to be harder than the demon's bet ever accounted for. The thirty-sixth Xanth novel makes an unwilling suitor both its central joke and its central romance.
