Stream of consciousness books can be very tricky if you are not already familiar with them and a lot of people give up because they find the prose to be too dense for them. If used properly, this method of writing can draw readers in, in ways that no other style can. But, in the hands of an amateur, the ever changing flux of thoughts can be a jumbled, distorted mess. One of the most famous authors to ever use this technique is of course Virginia Wolf and I highly recommend reading her essays on the topic if you have not yet done so already. "Modern Fiction" is one of her best I think. As for actual books, I would once again suggest giving Woolf a try. Her books, Mrs, Dalloway, To The Lighthouse, and The Waves are all prime examples of this form of writing.
