Firstly, the book was told almost always from Lex's point of view and only occasionally from Aiden's. I wanted to know why Aiden was an agnostic and felt that I didn't get to know him quite as well as Lex. The book could have delved into that farther and made Aiden's conversion more impactful. If he even was converted. The book wasn't all too clear on that point either. Aiden saw a realistic painting of Jesus on the cross, and it hit him to his core. However, he never really gave his life to Christ. I would have liked to have seen that. All Aiden said was that he was thinking about Christ more, not that Christ had any impact on him.
All throughout the book, Lex kept on saying that she would only marry a Christian. Define Christian. Most of the people in America say that they are "Christian" yet have no relationship with God. I believe most people believe to be Christian is to be just live a good life, go to church on occasion and so on. So Lex had somewhat of a flawed view there.
There were many volleyball terms that were not explained. Not everybody knows volleyball. I kept on wondering what the word shank means because I have never really played volleyball.
This book had deeper qualities and could have been truly more powerful if the author had dealt with them. However, Tang seemed to shy away from the deeper aspects of the book. I was somewhat disappointed in that.
I thought it was strange that the grandmother was so adamant on Lex getting a boyfriend. Even to the point of threatening to take away funding for Lex's volleyball team, getting Lex's dad's car repossessed, and kicking Richard (Lex's brother) out of his apartment. This seemed wholly unrealistic. However, it was hilarious to find out all the quirks in Lex's family, and I found myself smiling often.
All in all, Sushi For One? was entertaining. It didn't seem to drag at all. It had more of a lighthearted tone. Lex learned that she had to rely on God rather than on herself in the long run.
