Hidie Ho Neighbourinos!
Welcome to episode #3 of Sir Lancer Recommends!
The number three comes up a lot in the world of readers. So I figured for episode three we would focus on a trilogy. Actually, a trilogy of trilogies! and another trilogy! Kinda!
The first trilogy I am going to direct you towards has come up in a couple of Dragons and Jetpacks threads recently, and that is the Silo Trilogy by Hugh Howey.
