At least the descriptions are limited
At least, after the first sexual encounter. Still, if you're like me and don't like sex manuals in your romance books, this is a heads up.
Other than that, it's a good plotline. A man has twins to a wife who isn't into living in a remote rural town and competing with the river for her husband's time. When the twins are very young, she hightails it out and leaves the 3 of them to their own devices.
The father's business has been handed down through several generations. The twins were on the river from a young age - learning rapids, learning to be guides. At a young age, the girl twin, from whose point of view the story is told, hooks up with a musician, gets pregnant, & after around 2 years, he leaves, always promising to do something with his son but never showing up. Her twin brother wants more than rafting so he joins the USMC, and befriends a guy who joined up at 18 just to get a family of sorts, a guaranteed roof over his head, & a guaranteed 3 meals a day. The twin kind of adopts the guy, even bringing him home for Christmas once. Six days before his tour was up, he was on a classified mission and was killed in action. He refuses to die until his friend agrees to take the keys to his house and take care of his family since he can't, and so he shows up. At first, the female twin is angry at him, but realizes she is being unfair.
The female twin was running a bachelor party high risk level white water rafting trip with her dad. The rules were, no booze, no drugs, nothing that might impair the ability to focus. Just before the worst part of the rapids, which were a little higher than normal, they stopped for lunch and some hiked around the trails. The rapids were still safe to shoot if the rafts were OK and everyone was focused. The guy for whom the expedition was being held was the woman's best friend's fiance. The woman was his guide on the river. They hit a spot where first her dad's raft flipped, then hers did, and pretty much everyone was in the water. Someone got her dad back in the raft, but he was badly injured. They got out and realized the groom to be wasn't with them. They all hoped, as search and rescue looked, that he had simply gone further down the river, since he was experienced, but he had gone over the falls and died. It has destroyed her friendship and has resulted in threats, a town divided between those who believe it was a tragic accident and those who believe it was incompetence and that the girl virtually murdered the groom. Someone cuts her car's gas line, and it is a surprise who. Then someone burns down their office, which was close enough to their 2 houses to have caused more fires. Then her son and his friend go missing. While others hunt on land, the Marine and the woman use the river. They find the boys and use the emergency radio (no cell service) to let others know. Throughout the story, things happen that start mending the broken friendship. The perpetrator of setting the boys loose in the woods, and the arsonist, are both a surprise.
The Marine and the woman hooked up that Christmas when the twin brought his buddy home, and the buddy still reupped after that...later, she discovers he stayed to protect her twin. The Marine's life living in foster care or with friends and sometimes family who didn't want him make him disbelieve he can have a stable life...but he is great with the kids. Still, he is not used to real family life. The boyfriend the woman had been dating and she decide they're not really a good fit, but they remain friends since their boys are so tight. But will the woman and the Marine have a happy ending?
