Abbas, Cellular and Molecular Immunology is quite good.

It depends what you mean by "beginner". We had to read Janeway's and Kuby in our first-level undergrad courses and after reading others over the years, I still find that these are the best at covering the basics.

Agree with Catherine Habel.

Abbas, Cellular and Molecular Immunology is quite good book but its not for complete beginners! It has some parts that are not easy to understand. I can recommend  you One Stop Doc book, Immunology, the authors are Stephen Boag and Amy Sadler. The book is not big nor it's difficult to understand.

all best

KUBY

I think for a beginner kuby immunology is best. He or she also may may look for prescotts microbiology for overview of immunology .

Kuby Immunology and Janeway's Immunobiology are the two best Immunology books. I would highly recommend reading both if you want to gain in depth knowledge, and have desire to stay in Immunology field in your academic carrier.
