[Note: for some reason I appear to have spaced on posting this book report when I read the book back in February. Doing it belatedly, for completeness.]
Winding up the original Amber pentalogy with The Courts of Chaos. After the shocking and fantastic events of the first four books, the hero/narrator Corwin sets of on a perilous, probably futile, quest to save Amber from destruction by the forces set in motion by a rogue Amberite.
Not that it matters, but: I read these books when they first came out in my college/grad school days. On re-reading, I find it's more difficult to keep track of the characters.
Also: I note that there's an alleged TV series in the works. (That's from the summer of 2016 though, so I'm not holding my breath.)
