Jaded Billionaire by Jill Snow

Ethan Thomas is disillusioned after selling his company for billions and discovering all the people he cared about are now only interested in him for his money. Needing to get away, he heads to a campground in Sweet Mountain, Montana. It’s the off-season and he is assured all the other cabins will be empty. He’s after complete solitude which is why the last thing he needs is a city-slicker faux camper in the cabin next door. Especially one who doesn’t even know how to boil water over an open fire.
Lily Ryder doesn’t even know how to boil water over an open fire. Or on a stove for that matter. But she can’t pass up the opportunity for a big promotion at the newspaper where she works. All she has to do is spend one week at a campground and she’ll steal the job right out from under the nose of her rival. Camping, even in a cabin, turns out to be a lot hard than she expected, but the last person she’s going to turn to for help is the Neanderthal that almost shot her dog.
They could just ignore each other, but Sweet Mountain is hiding a secret, one that could change both their plans forever.
