Ebook: Elements of Modern Algebra

This is definitely one of my best math books. The main feature of this book is that the readers feel very easy to follow the provided concepts and understand what is important. I really don't know any other book as good as this one. Probably only David C. Lay's "Linear Algebra and Its Applications" can compete with this one. I truly recommend anyone who studies modern algebra to take a look at this. Good luck!
