Unfortunately there's not too much to see on this Amazon preview thing, but it appears to be pretty misleading. I don't talk about the unusual appearance in a cartoon-like style, which can be fun and a nice motivation to start with a subject. My main criticism is that it, despite its modern looks, this book seems to be pretty oldfashioned as a textbook for quantum theory. From the back text I guess, it uses very outdated ideas like "wave-particle dualism" and the inaccurate statement that the photoelectric effect would prove the existence of photons in the sense of some kind of particle-like behavior of the electromagnetic radiation field. Both are overcome in 1925 with the development of "modern quantum mechanics" by Heisenberg, Born, Jordan, Pauli, Dirac, Schrödinger, and others.
Further, the Heisenberg uncertainty relation does not tell that there's a limitation in the accuracy we can observe nature, but according to quantum theory (more precisely Born's Rule about the probabilistic meaning of the quantumtheoretical notion of the state of a system) certain observables really cannot have determined values simultaneously, no matter in which state the system is prepared. The most famous example are position and momentum.
There is an overwhelming evidence for this point of view to be really true, no matter how "weird" we may think this is.
Last but not least, the statement that quantum theory is notouriously difficult is quite demotivating and not really true. Of course, it's a much more abstract point of view on the physical world compared to classical physics (including relativity theory), but that's how nature is, and it is well doable by a student in the 2nd-3rd year of his or her studies.
I'd rather recommend more modern real introductory textbooks to learn what quantum theory really is. My favorite for a beginner is
J. J. Sakuray, Modern Quantum Mechanics, 2nd edition, Addison-Wesley
(2nd edition, because it has some interesting additional material compared to the 1st).
I'm also looking forward to the upcoming textbook by S. Weinberg, which is expected to be published at the end of this year. So far any textbook of Weinberg's has been among the best expositions of the treated subject be it "Gravitation and Cosmology", the three-volume compendium on relativistic QFT, or "Cosmology".
