It's the fourth book in the series, it's still absolutely delightful to watch Brennan's mind at work and her world unfold. She's really good at writing to her dual audience of supposed early 20th century memoir readers and actual 21st century fantasy readers. And Isabella is still amazingly fun to follow around. I can't wait for the next book—there's all this information about dragons that is slowly adding up and, seriously, I can't have book 5 yet?
