Read it allllllllll. Absolutely my favorite series in its full capacity. Just such a great story, and the back and forth between the individual series' perspectives is a very unique and interesting way to tell this large tale.

Anytime someone talks about it, I can't help but feel jealous that they can read it for the first time.

It is a heavy lift, if you decide to chug theough it, but well worth it, IMO.
