Proxy

When the ex-wife of private detective Ray Thomas' sworn enemy hires him to find her daughter, he soon learns there's more to the illegal implant technology known as Proxy than body-swapping.
Proxy dealer Elijah wants to know who's trying to kill him, and how it's connected to a new kind of Proxy that's hit the streets.
What they each discover on the streets of a near-future London crippled by multiple pandemics has the potential to change the course of civilisation...so long as they can stop the wrong people getting their hands on it first.
