Ombria in Shadow by Patricia A. McKillip
My rating: 4 of 5 stars

Anyone who reads Ms. McKillip knows the kind of fantasy she writes. Her stories always seem very dark though they often have bright(ish) endings. This one is about what happens when light and shadow overlap. This is only the third McKillip book I've read, but I have become a huge fan. I enjoy her non-traditional style of fantasy with its darker tone.
