ron Gold by Pierce Brown is the introduction to a second trilogy in the Red Rising universe. The first trilogy ended with Morning Star, which you can read my review of here. I enjoyed Golden Son in the first trilogy, but books one and three were average at best. Still, I wanted to continue the story, so I picked up Iron Gold and started reading. But was it worth it? Did I enjoy it? Was Iron Gold even a necessary book, or should the story have been left alone? These are the questions I will be answering in this spoiler-free review of Iron Gold by Pierce Brown.
