Holy mindf*ck! That's what I thought after reading this series.
First, the criticism: this series does tend to echo other famous erotic romance series, notably Fifty Shades and Crossfire. Then again, won't most ER novels that deal with emotionally scarred billionaires?
Second, for the praise: I enjoyed Ms. Paige's writing. The characters were fully developed and felt like real people to me. None of them were perfect, most were scarred or flawed in some way. Dysfunction ran rife throughout both Alayna's and Hudson's families and their relationships.
Third, I liked that Alayna had worked through her therapy and felt that she was successfully living in recovery. She knew her triggers and avoids them whenever possible. She also did go back to meetings or reach out when she felt that she was going to slip back into her self-destructive behaviors. She was strong and didn't want to break or be broken and fought for her recovery. I admired that in her. I also enjoyed that she helped Hudson, and vice versa, with healing and not falling into old patterns.
One thing I would have liked to have learned was whether there was some mystery with Chandler and if so, what was it. I felt like that was a loose end. ETA: upon a second read, it is lightly touched on, but still felt like doubts were left.
After finishing the series (and I couldn't put it down and read it at work, while riding in the car, and at home) I felt like I'd need to reread it again, just to see if I would catch any clues. One bombshell was one I had figured out but the other was something I hadn't or didn't want to consider.
If you're a fan of the ER genre, you won't be disappointed.
