The concept that makes this story unique isn't revealed until three-quarters in, and yeah, it ends on a dangling to-be-continued. This hidden counterplot was cool except I figured it out 32% into the book--when Nash blurted his father's secret. The way he said it, the pronouns he used, I knew what was going on. This would be fine except Olivia didn't figure it out with me. If the reader stays a step ahead of the heroine, without any help from supporting POVs--as was the case here--the result is crippling. In fact, the truth didn't sink in for her until it was shoved in her face, and even then she was in sputtering denial. This made the concept inconceivable, and made her look like a moron. Nevertheless, ML's writing was polished and the sexy romance was addictive. I couldn't put it down. I didn't want to put it down. I'll read more from this author, including the sequel to this book.
