Understanding this complex novel was a challenge. I almost gave up, but decided to read it as four separate novels, using the chapter names. First I read Zeno/Seymour, then Omeir/Anna, then Aethon's story, and finally Konstance, and then the whole novel clicked! I am very glad that I did not pass on this gem. I opened this book, Mr. Doerr, and I am amazed.
