Loosely related to finding new books to read, I have another question.

Does anybody else sometimes start a series, stall in the middle and then want to go back to it later? Many years later? And then, how do you refresh your mind on what's happened in the previous books?

Case in point: I struggled with Clan of the Cave Bear through several starts and stops, then one time I got excited about it and read it through. Then burned through the next two, Valley of Horses and The Mammoth Hunters. Then stalled again about 10% of the way through Plains of Passage. Now there are even two more after Plains. But the last time I touched Plains was well over a decade ago. Maybe two decades.

Is there like a "Cliff Notes for Novels" site somewhere that I might be able to re-learn what's happened in the series up to the point where I stopped, so I can pick it up again without re-reading from the beginning? Some summaries, but more detailed than what you get in the sales blurbs for the books on Amazon?

p.s. - I did look at the Cliff Notes website, but searching for these books didn't turn up anything. There are book plot summaries on Wikipedia, but I was hoping for a little more detail than those provide.
