I'm busy working my way through the book, writing up notes on clues to try and gather everything in a coherent form. Plus whenever I get AK related Echoes and other clues in game, they go in to the notes as well.
I feel like I'm getting close to pinning down the location of the lab and where she lived (although I think that's outside the playable area as in the book she constantly talks about home not being in Manhattan).
P.S. My order from Amazon was listed as delayed due to being out of print, despite me pre-ordering it. But it eventually turned up only a week after game release. So keep those fingers crossed!
I just finnished pick up all intel in game and have been caught up in the grind for the best gear. I need to read my copy and compile notes. It's an activity for this coming weekend as this week will be tied up attempting the Incursion and the new assignments. Do we have a central location/discussion board or topic for the "New York Collapse" content?
Not that I know of. But there is substantial reddit page about it I don't want to peek there and won't link to it because it does spoil a lot of the content. So if you don't mind it just google and I am sure it will be one of the top 5 finds.
On another note, my local book store beat Amazon and found me a copy of the book - I am collecting it today. I am really really happy.
Edit.
Ok we are all grown ups, so it's up to you whether or not you want to read the page. They made lot of good work on this book, so if you share information from this page make sure you link back to the source:
Aren't the caches thoses rewarded in the Agent Intel page, mission 4 ?
