Ms. Couper pulled a fast one. I went into this story knowing that I was going to dislike James and I came out even more intrigued by him. That are various layers to both James and Sienna that are hard to endure but kept me enraptured all the same. What neither understands is there is no black and white when it comes to the heart. That gray area almost always wins. The Stubborn Billionaire is a complex story that begins with revenge and ends with love.
