Query: THE FIRST book to read on quantum theory

Of all the books that I've read on quantum theory that do not use calculus, this is probably the best. He is clear and succinct and ties things together in ways that click (at least for me). Some others that I'm reading that I'm comparing to: Quantum Theory - A Very Short Introduction by John Polkinghorne (good, but very quick pace), The Story of Quantum Mechanics by Victor Guillemin (also very good, might come in second), Thirty Years That Shook Physics by George Gamov (alright, particularly good for anecdotal stories from one who knew these guys), and Physics and Philosophy by Heisenberg (good, but I'm not too far yet, clear, and a good writer).
