The Rise And Fall Of D.O.D.O. was a really good book, and I hope there’s a sequel because nobody should be allowed to end a book with that much unfinished business left. There are so many possible subplots to deal with that, (now that I think about it), there should just be a series.

@toddgrotenhuis There's not a hard-back sequel or series as such, but the Bound app has a serial called the D.O.D.O. Files which has weekly episodes. Need to see if the app's accessible.
