Just on Kindle, which can be downloaded as an app on most e-readers.
I downloaded it to Kindle last week already and have been reading it - spellbinding, absolutely spellbinding stuff.
Again, like your EF&D series, the scenario is well researched and scary plausible.
It is my bed-time reading and I have to force myself to stop and go to bed, so I can get a decent night’s sleep.
I used to be a prolific reader many years ago, and just recently acquired a Kindle to take up my old hobbie again.
And Matt Bracken’s writing is addictive.
I’d have to root my nook to run the kindle reader.
