An Angel in the Mail (Oregon Trail 2) by Callie Hutton

An Angel in the Mail, set in 1861, unites Angel Hardwick and Nathan Hale, father of five, who is desperate for a wife to straighten his life out.

Nate’s looking for someone who loves children and can easily take over the cooking, cleaning, and laundry. Instead, he is getting Angel, whose culinary knowledge consists of weekly meetings with Cook to decide the family’s menu.
Angel , a strong-minded young woman, is resigned to her fate and determined to make the best of her situation. But will her new husband allow for mistakes? Or will he send her packing when she burns meals and misplaces children?
Nate just wants a peaceful, well-run household, without the distraction of an attractive wife. However, his beautiful wife with a very distractible body is not giving him peace. Somebody lied, because despite what he was told by the Bride Agency, this beauty knows nothing about running a home, but she sure sets him on fire at night.
To survive, Nate and Angel have to come to a working arrangement, but will they be able to find a happily ever after with someone working behind the scenes to destroy their relationship?
