I remember reading a SciFi or Cyberpunk story some three or four years ago. It was an E-pub and I remember the title containing some color, but I can't seem to find it again.

The story is about some security expert or hacker that is working for a company. The main character get messages from a (deceased?) friend or old colleague, and over time does join a church or cult to try and find out what happened to them. I believe that there was some kind of AI involved.

It is *not* [Neuromancer][1], [Count Zero][2], [Mona Lisa Overdrive][3], which I read in dead tree format between 2005 and 2010, and loved. The book was however suggested to someone I knew because I said I liked the [Sprawl Trilogy][4]. It also wasn't [Virtual Light][5], which I read around 2013.
