Will the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever? The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology: there is too little visible matter to account for the behavior we can see. Over ninety percent of the universe consists of ”missing mass” or ”dark matter” - what Lawrence Krauss, in his classic book, termed ”the fifth essence.”In this new edition of The Fifth Essence, retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology: the fate of the universe and the ”cosmological constant.” With a new introduction, epilogue, and chapter updates, Krauss updates his classic for 1999 and shares one of the most stunning discoveries of recent years: an anti-gravity force that explains recent observations of a permanently expanding universe.

If one is interested in learning about cosmology and getting a basic understanding, this is not the best place to start. There are other books available, including by Lawrence Krauss that would serve as a better place to start. However, if you already have that base understanding, and want to learn more about the question of the missing mass of the universe, then this is definitely the book for you. What makes a good science resource for me, is something which pushes beyond my current level, and challenges me to learn more, and this book does that. This means that after reading other books and papers, I can return to this book for a second reading, and get even more out of it.
Where the book could do even better is in the area of supplemental material. The first chapter has about 20 footnotes, which is what one would expect. The entire rest of the book has only 4 footnotes. It is not the case that footnotes are always useful, but the lack of footnotes is never useful. Similarly, appendices can be very useful ways to bring readers additional information which is indirectly useful to the material in the book. This book has two very short appendices, one on “Orders of Magnitude and the Scale of the Universe” and one on “A Really Brief History of Time” which are all well and good, but there are other supporting topics which probably would have been useful to include an appendix covering. Lastly, there is no bibliography included at all, which is very unusual for a book on science. Certainly, Krauss mentions resources in his chapters, but would be useful to have a list of those resources (and other additional works) collected at the end of the book, and the absence of a bibliography seems rather strange.
