Immoral Games by Marissa Farrar

I’ve been stranded in a cabin in the wilderness with my two gorgeous but damaged stepbrothers, and my overprotective stepfather.
We’ve crossed boundaries that in normal society would never be traversed, and now we can never go back to what we were.
We thought the biggest threat to our lives was Mother Nature.
We were wrong.
In desperation, we tried to reach safety, but a new danger has emerged.
Now we’ve been taken by gun-runners who know who we are.
They force us to play their games for their own entertainment while they try to figure out what to do with us.
The relationships that saved our lives are being tested to the extreme.
They’re trying to break us, but we won’t give up.
Not when we have each other.
