Mail Order Cowboy by Victoria James

Hope Roberts has a strict No Cowboys Allowed policy. Between raising her daughter, running her business, and trying to settle into her new ranch, Hope has no room for romance—especially when it comes to cowboys. What she needs is someone to help fix her ranch. But the only person to respond to her ad is the one man Hope still blames for her husband’s death…

But Dean doesn’t trust a complete stranger to keep Hope and her daughter safe. And despite their troubled past, he’s still the best cowboy for her job.
Bit by cautious bit, Hope’s little family of two is making room for the man she once thought of as her enemy. Until one day, Dean looks like the perfect exception to her “no cowboys” rule. But he’s been keeping a secret from her that could destroy their newfound family…
