Read: Susan Cooper - King of Shadows

I purchased this book a few years ago, interested to read something new by Susan Cooper - I have loved and re-read her 'Dark is Rising' series many times since I discovered it as a child at the town library. It has some similar characters and emotions, but overall it lacks the same powerful mythology. I recently re-read it, because I was looking for a book to take along one day on the subway (I didn't have much room in my bag that day, and it's a slim book). And I think I'm ready to let it go - I'm purging my bookshelves, and don't think I'll read it again.
