His Mail-Order Bride [EPUB ebook] 

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 only to stay until it’s safe to leave. Except marriage to kind-hearted Thomas is far more complicated-and pleasurable-than she ever imagined!
