A satisfactory conclusion in my opinion. The book ties up all I wanted to see happen from the first book, I doubt I'll read any more. Some interesting things occur, but it begins to feel a little repetitive already. I can't imagine being wildly impressed with any of the "further adventures." 
 It reads rather like a cheap superhero comic, as some have said. The villain is easily foiled on several occasions, and he rages and threatens like any villain worth his salt. Tarzan in turn, tells the villain where he can go if so much as looks wrong at any of his lady friends. So goes much of the book. Throw in more treasure, a few lions and thugs and a love triangle, and voila! Instant entertainment.
