Ok, I messed up. I thought this was book #3 of the series and was about 100 pages into it before I discovered I was wrong. I thought a lot had happened between Legend of the Jade Dragon and this one, but the story still ran smoothly, so I thought that was just the way she wrote it. Just goes to show that you don't have to read all series in the correct order.
This has been my favorite in the series so far. A wonderful mix of ghosts, both human and cat, a lost love and a lost pet.
