This is a nice pocket-sized guide to consciousness. Actually it’s a guide to the problem of consciousness, since there is no consensus on what consciousness is or even exactly what the word means. Blackmore is even-handed regarding the various competing viewpoints, though it may all be slightly coloured by her own views, which are heavily influenced by Buddhism. And if you think that’s an incongruous stance for a hardcore psychologist/philosopher to take, then you really should read this book.
