Query: Great book if you want a REVIEW of Algebra 2

I am currently taking Algebra 2, cannot find anyone in the class that likes the book. The author gives very few examples, too brief on discussing topics. This book would be great for someone who has already had Algebra 2 and wants to do a review. I am now reading other material to understand what this book is talking about.
