A competent, if a bit uneven, introductory textbook in contemporary epistemology. Lemos adopts a fairly straightforward format: every chapter charitably discusses some theory/ies, while also providing a number of objections. There's minimal overlap -- any overlapping material becomes more evident toward the end of the book -- so you can practically read whichever chapter you find the most interesting. Lemos is a good writer, one that has honestly tried to write a comprehensive introductory textbook.
Yet, there are important omissions. For instance, knowledge-first epistemology is nowhere to be found, while the chapters on the a priori and naturalized epistemology feel underdeveloped -- the latter, in particular, seemed to me overly biased too. Moreover, while certain chapters are fairly dense and rewarding (Tripartite theory & the Gettier Problem, Coherentism and Foundationalism), others just pack too many things together, thus giving a very superficial overview. For example, the chapter on scepticism manages to include discussions on Relevant Alternatives, Moorean Common Sense, and Contextualism in less than 25 pages.
Despite all that, I would still recommend this book to the uninitiated who wants to supplement his understanding of the field and get a better grip on the very general discussions that take place between troubled, contemporary epistemologists.
