When I first saw the book Alice in Lace, I thought I was going to like it. And as it turned out, I love it! I love books about life and being a kid. And Alice in Lace is just that kind. It’s a humorous book about being thirteen and the problems kids might face. Alice and her friends get a strange assignment from their totally cool teacher, Mr. Everett. It was like playing the game of “Life,” but you had to act it out.

So Pamela is pregnant, Elizabeth buys a car and Alice gets married. Well, of course, Pamela wasn’t really pregnant, but she walked around with a pillow under her shirt to get people’s reactions. Elizabeth didn’t really buy a car, but she went to the car lot and made the sales guy think she was. The whole class got assignments like these! I would love to do something like that for school.

In the book Alice has a lot to think about. “Getting married is hard!” Alice says. She has to plan the ceremony, the honeymoon, find a place to live, pay for furniture and two months’ rent and food. Maybe she and her “husband” could work it out — if they were getting on fine!

Although this book was funny, it really made me think about how problems like these could really mess up your life. Take teenage pregnancy for example. How could you have a baby and stay in school? You couldn’t find a babysitter every day to stay with your kid. A child really consumes your life. I understand what the teacher was trying to do. He was trying to discourage the class from getting into these problems by giving them a glimpse of life. As someone about to become a teenager myself, I can say sometimes a story makes you think about what’s up ahead.

Overall, I would say this book is wonderful. My favorite part of the book is discovering that if I like it, there are seven other Alice books I can check out at my local library. I love this book, and I hope you will too.
