His Mail-Order Bride

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
A Wild West wedding! 

Thomas Greenwood expected his mail-order bride to be plain and pregnant—not a willow-slim beauty! She's clearly no practical farmer's wife, but she's his chance finally to have a loving family… 

Runaway heiress Charlotte Fairfax fled the possibility of a forced marriage, yet now, assuming a stolen identity, she's wed to a stranger the moment she steps off the train! She plans to stay only until it's safe to leave. Except marriage to kindhearted Thomas is far more complicated—and pleasurable—than she ever imagined!
