Book Review by: Danya, age 11, Israel One Is Not a Lonely Number is a fiction book about a thirteen year old girl named Talia Schumacher. Talia is an only child. You might think that it is fun being an only child. You can get more attention from your parents, have more time to spend with them, have a quiet house, and not have to babysit your baby sibling. You do not have to share a room EVER, and even have more privacy. But for Talia it's totally not like that. Instead of siblings, her parents invite guests to the house and Talia is getting sick and tired of that. If you like stories that sound real you should read this book.
