Você está descrevendo a série " WebMage " de Kelly McCullough.
Por revisão da N.Trachta:
Mr. McCullough does a very good job of merging our current world with that of Greek mythology. The Fates are very real, the Furies bite at you, and Eris is the goddess of discord (as Mr. McCullough points out nicely, the hackers goddess). The fascinating thing in this series is that the gods and goddess's use computers to execute their magic, something that Mr. McCullough sells very nicely by having the gods computers being living trolls (mainframes) and goblins (laptops/pcs).
