Doerr’s writing opens new lines of knowledge for me: I research about as much as I read in all of Doerr’s novels. Cloud Cuckoo Land integrates story, emotions, and human desires as the reader juxtaposes story within and story without. This novel is heavy and light and dark and whimsical. Both my bones and heart and sinew are strengthened and nourished in this Cloud Cuckoo Land. Amazing. Thank you, Mr. Doerr!
