The villains trilogy begins with "Omega" and it's absolutely brilliant. The story greatly expands on Omega's character and backstory, while cleverly still leaving some things unclear, his characterisation is fantastic and Ian Collier, reprising the role from "Arc of Infinity", plays omega brilliantly. Peter Davison is given a lot of interesting things to do in this story and his performance is brilliant.

The story is fantastic, it keeps you second guessing until the very end, and has several incredible twists, the main twist of the story in particular was genius and is one of those twists that changes everything. This story is a must listen, as is the whole Villains trilogy.
