J.M. BergerI'm holding an everywhere-but-Twitter promotion:
Optimal, my dystopian novel about a world run by algorithms, is free to download on Kindle through Friday.
Feel free to share this link anywhere that isn't Twitter!
Mark de Vries 🇪🇺@intelwire Does it come as an ePub or propriety Kindle format?
@markdevries Sorry, yeah, it's a Kindle exclusive (there's a print version but not included in the promo).
