This was a refreshing addition to the NA genre. The characters are smart, respectable, and not blind to the obvious. I never felt like hitting Tess or Dylan over the head and shouting, "Wake up, idiot!" What a relief that was! I feel like a common thread I've encountered lately is "smart girl being ridiculously stupid and blind." What does that type of character have to offer? Not much. It often leaves me wondering what the male MC sees in this girl. Thankfully, Tess is intelligent and never forgets that. Her intelligence doesn't end with academics but also carries over into her personal life. She has real conflicts and internal pushing and pulling but handles it like an intellectual person and not some dunce.
I found Dylan to be refreshing as well because he was a good guy that was still desirable and respectable without ever treating people poorly. I'm all about the "bad boy" characters, but there comes a point where bad boy becomes douche bag jerk and the reader is left searching for a redeeming quality. Dylan maintains his masculine qualities and attractiveness through the whole story without being a pushover or pansy. The good guy can be more than the overlooked best friend; he can be desirable, strong, and drool-worthy.
One & Only is catching, enjoyable, and a breath of fresh air in the NA genre. The characters are easy to care about and respect. I really enjoyed reading this story and I am looking forward to Hannah's story.
