I am a lover of combinatorics, and I have read quite a few on the topic. This one is as good as any. Lucidly written, you can pretty much dive into any chapter, reading, scribbling, racking your brain, and come away with a deep sense of satisfaction and pride and vanity:). Price is so resonable with regard for its extensive content. You get a feel that the author really wants to share with readers his love and joy for the subject and not just to make some money. Thank you, my dear professors!
