I've never actually read this before so was surprised to find it's a collection of short stories, even more so that only a few are actually about Mowgli. Those were my favourites and I particularly enjoyed the story with Kaa and the Bandar-log. Kaa is a complex and dark character, clearly dangerous yet someone to have on your side. The language, mythology and story telling were fantastic, very enjoyable and understandably it's a classic. More Mowgli would have been nice though. I really should have waited to read this in India rather than China.

Additional (20/08/12): Seeing as I read the kindle versions of both Jungle Books I subsequently bought the small hardcover listed above with a foreword by Neil Gaiman (which is brief and seems aimed at a young audience). I liked the Mowgli stories and this compiles them all in the same volume (along with Rikki-Tikki-Tavi); I thought it was important to have it physically on my shelves. It's a small size hardcover, study and should last though the cover feels too plasticy for my liking.
