He's her older brother's best friend and completely off-limits. She's got a way with horses...and a heart condition. Can Beau and Charlotte navigate close quarters to find their happily-ever-after?

Beau Peterson has been to seventeen cowboy weddings over the years he's lived and worked at Three Rivers Ranch. And now, his best friend is getting married, making it eighteen.

He used to be a real ladies' man, and he didn't get serious about dating until a few years ago. Then he couldn't find anyone worth being serious about. Then, as he's conducting interviews for a new Stable Manager at the ranch, he watches as someone faints right there in his kitchen.

And not just someone. Someone he's met before and been told to stay away from.

Charlotte Wisenhouer. His best friend's younger sister.

Charlotte has been nannying for her brother and his wife, but their last child is now in school. She used to train and show horses, and she's desperate to get back into the saddle. Literally. Her heart condition has kept her out of it for years, and everyone around her has kept a close eye on her ever since her diagnosis in her late teens.

She's sick of it, and now she's ready to strike out on her own. So she doesn't tell Beau about her health issue, and she's thrilled when she gets the job.

However, there's a catch. The cabins at Three Rivers are full, and the only place for her to live is in the foreman's cabin.

With her very single, very attractive boss: Beau.

He's not sure if God is playing a trick on him or blessing him for his patience and hard work, both in his personal life and around the ranch. Charlotte knows her brother wouldn't approve of her budding relationship with Beau, so she does what she always does: She doesn't tell him.

But the truth has a way of always coming out, and when it does, will both Beau and Charlotte get burned? Or will they be able to forge their way forward to a future together?
