Persistence. The network that stripped anonymity from its users. Always on, always watching, always recording. Complete access to anyone, at any time, at any location. Your identity distilled to a key created from your genetic makeup.
Shift. The drug that modified one's genetic makeup. A tiny piece, an entire strand, entirely up to the user. To Shift one's self was simply a needle away. One poke and it would all change.
The price of that injection, however, is to give up your identity, give up your former life. One individual will discover just how costly that price is, to battle the oppression of a true surveillance state.
Shift moves at a fast pace from the first page, but the best parts and some of the clever techniques the authors invented to dive deeper into PoV. If you're looking for a short fast SciFi similar to Ready Player One then shift is a great read, but more importantly, if you're a writer and want to study deep PoV, read Shift.
