Review posted here. 
 I haven't read any of Viv's other novels, written under her real name Diana Peterfreund, but I jumped at the opportunity to help with One & Only because I've heard really good things about her work. I'm so glad I did. I freaking loved One & Only. New adult is brimming with self-published romance novels, and honestly, most of them just aren't any good or at least aren't very polished. Not only did Viv's publishing experience help her shape a polished novel that can overcome the stigma of being self-published, but her writing helped her create realistic and wonderful characters and set them in an engaging story. Honestly, I couldn't put this one down. It took me a couple hours to just read it right through. I could sense that the other shoe would drop, but it didn't happen when I expected it and it didn't happen exactly how I imagined it would either, which kept me reading. 
 I found the characters really well-developed. Tess is a pleaser with big dreams. She's spent her life trying not to rock the boat of her precarious relationship with her dad and witnessing her mother do the same. So when Dylan comes around the first time, she's afraid he'll prove nothing but a distraction from her studies at State. I really empathized with Tess, who wants big things and is just told no time after time. She's afraid of doing things that will make people, particularly her father, not love her. I really like that One & Only is really about Tess learning how to stand up for herself and take what she wants. It's not that she learns to be selfish, but she figures out how to be confident and assertive. I also really liked Dylan, who is not a perfect person. He makes some pretty serious mistakes in One & Only, but he takes responsibility for them. A guy who tries to do the right thing but owns up when it wasn't the right thing at all? At the risk of sounding like Paris Hilton, that's hot. 
 You know what else is hot? The romance. I'm not talking about the scenes in Dylan's dorm rooms (although those are definitely steamy!). I'm talking about the chemistry between Tess and Dylan. The force is strong with these two. They've got a serious physical connection that is absolutely palpable, but they also challenge each other mentally. In the excerpt, Tess and Dylan have just completed their summer project, and that puts them in a mental high that leads...well, you'll just have to read it to find out. I love that this book does focus on two intelligent characters who pretty much pop mental boners whenever they work with one another for various projects (Yes. Brain boners. Totally a thing). This romance really is proof that guys like smart girls, even if it's fiction. As for the actual "romance scenes," I found them to be tasteful and just enough. They don't fade to black, but they don't get super gross and raunchy. It's mature content, yes, but it is actually mature in the sense that it's not crudely underdeveloped smut. 
 In short, One & Only is a lovely romance that defies the common belief that new adult novels lack characterization or plot. I felt connected to the characters, and the plot was both engaging and believable. I haven't talked much about the plot because I don't want to give too much away on that front, and it is much more character driven. I wouldn't classify it as a fluffy read by any stretch, but it's an easy read for a quick escape, and I really recommend it.
