I was recommended Brainstorms by Dennett, which was slightly tricky to get hold of. It feels very worthy but I wouldn’t call it riveting. I don’t think Dennett does riveting, though I think he has his own sort of appeal, and did like the way Intuition Pumps was put together. I think Consciousness Explained is a more populist effort to, well, explain consciousness, though I haven’t read it.
Susan Blackmore’s also done Conversations on Consciousness, which is transcripts of interviews with notable academic figures on the subject, and is sitting in my to-read pile. She wrote The Meme Machine as well, which is more about memetics than consciousness, but does put forward some material on the topic, and is a quick read at <300 pages. As much as I want to like her, I personally find Susan Blackmore’s writing a little annoying. YMMV.
Mind Hacks isn’t about consciousness, but it’s a very interesting CogSci book about how your brain pieces together the world in kludgey-messy ways, and how mental faculties we take for granted will fly apart at the seams if given the right corner-case. If you liked those aspects of the Consciousness VSI, you might like this.
Blindsight is an excellent hard sci-fi novel which you might want to consider reading if you like that sort of thing, and I’ll say no more about it.

If you liked Blindsight’s ideas, you should definitely try to read Being No One: The Self-Model Theory of Subjectivity by Thomas Metzinger. Apparently Blindsight was heavily inspired by it. This is what the author has to say about it:
Let’s get the biggies out of the way first. Metzinger’s Being No One is the toughest book I’ve ever read (and there are still significant chunks of it I haven’t), but it also contains some of the most mindblowing ideas I’ve encountered in fact or fiction. Most authors are shameless bait-and-switchers when it comes to the nature of consciousness. Pinker calls his book How the Mind Works, then admits on page one that “We don’t understand how the mind works”. Koch (the guy who coined the term “zombie agents”) writes The Quest for Consciousness: A Neurobiological Approach, in which he sheepishly sidesteps the whole issue of why neural activity should result in any kind of subjective awareness whatsoever.
Towering above such pussies, Metzinger takes the bull by the balls. {Spoilers for Blindsight, use rot13}: Uvf “Jbeyq-mreb” ulcbgurfvf abg bayl rkcynvaf gur fhowrpgvir frafr bs frys, ohg nyfb jul fhpu na vyyhfbel svefg-crefba aneengbe jbhyq or na rzretrag cebcregl bs pregnva pbtavgvir flfgrzf va gur svefg cynpr. I have no idea whether he’s right— the man’s way beyond me— but at least he addressed the real question that keeps us staring at the ceiling at three a.m., long after the last roach is spent. Many of the syndromes and maladies dropped into Blindsight I first encountered in Metzinger’s book. Any uncited claims or statements in this subsection probably hail from that source.
Every time I’ve heard someone mention Being No One, it’s been accompanied by some statement along the lines of “this book was above my level”. This has certainly piqued my interest, but it hasn’t instilled me with confidence about my ability to tackle it.
I’ve tried reading the book several times; I feel that the problem isn’t so much that the content is intrinsically difficult, but rather that the style of writing is generally terrible. Paragraphs are spent on something that could have been expressed in a sentence, and every now and then one gets the feeling that the book is written using English vocabulary and German sentence structure. A good editor could have cut down the length by hundreds of pages without losing anything essential.
The content is great if you can work your way through it, but despite that, I’ve still never managed to work my way through the whole book.
Nice discussion of Metzinger’s theory of consciousness. His basic claim is that what humans tend to think of as a “self” is what he calls a “phenomenal self-model” (PSM). As the name suggests, the PSM is the brain’s model of the organism as a whole, and includes things such as a model of the organism’s body. The PSM is situated within a broader world-model of the environment that the organism exists in. Metzinger claims that the reason why we experience there being thing such as “selves” is that there has been no evolutionary advantage in seeing the PSM as a model—we do not see the sophisticated computational machinery which produces it, and thus experience it as something self-contained and essential, rather as something that’s constructed from parts for the sake of enabling better information-processing.
Metzinger’s book discusses a number of experiments as well as details of what our conscious experience is like and what the reasons for that might be.
For example, humans perceive time as a kind of eternal present: everything we experience is experienced as happening “now”, and even when we recall a memory of the past or think of the future, it is experienced as us remembering or planning something right now. But one could imagine a mind that didn’t have any conception of an immediate privileged now. Metzinger doesn’t go into detail of how this kind of a different mind would represent time, but personally I could speculate it as having just mental representations of events with different timestamps, with increasingly broad probability distributions on those events that had not yet been witnessed but which were extrapolated to happen, or of which sufficient time had passed that the memories might be becoming uncertain...
Metzinger suggests that the experience of a unified now emerges from the need to take quick action in response to threatening situations in the environment, and to provide all of the subsystems in the brain with a shared temporal frame of reference:
Although, strictly speaking, no such thing as Now exists in the outside world, it proved adaptive to organize the inner model of the world around such a Now—creating a common temporal frame of reference for all the mechanisms in the brain so that they can access the same information at the same time. A certain point in time had to be represented in a privileged manner in order to be flagged as reality.
Metzinger also suggests that this sense of a Now is part of what enables consciousness as we understand it: experiencing ourselves as being embedded in a constantly-developing Now is a fundamental part of human experience and consciousness.
The weakest part of the book is the last third, where the topic suddenly switches into that of ethics. The discussion in this section seems quite disconnected from that of the previous sections, and Metzinger starts talking about issues such as national drug policies and whether meditation should be taught in schools. A part of this discussion is justifiable as it touches upon the question of the effects that an increased understanding of consciousness research will have on society, but the whole discussion mostly comes off as superficial and not very well-argued. (Though I will admit that I started skimming this section pretty quickly.)
Nonetheless, overall Metzinger paints a very interesting picture of his theory of how the brain might work, though there’s still a definite speculative vibe around it all.
Well Blindsight impressed me enough, that I’ve started The Ego Tunnel. In short, the idea of unconscious intelligence bothered me. My intuition says that consciousness could be what happens when something tries to model its intelligence and actions, but of course that hardly explains anything. While I feel like it’s unlikely I’ll find many good answers, it is interesting enough to be enjoyable to read.

Metzinger’s The Ego Tunnel is the popular-audience version of Being No One.
My review of the Ego Tunnel:
Well Blindsight impressed me enough, that I’ve started The Ego Tunnel. In short, the idea of unconscious intelligence bothered me.
