Panacea Omega

A Panacea Corp competitor rushes their new product—a shot that alters DNA—to market so that people can enter the metaverse without an embedded chip. Unconcerned that the shot is permanent and they'll never be able to leave again, people return to the metaverse in droves and many enter for the first time. But there are side effects that have far-reaching consequences. 

Panacea Omega is book 3 in the Panacea Trilogy. For book 1 see Panacea Genesis.
