Wow, even better than 22. This book gives us a backstory for how Orion became Optimus. Most of this takes place in the past, and I felt the parts in the present interrupted the flow mostly, but man was this rich in story. A nice slow read. Art is top notch, I'm loving Milne's work so much. Good to see Sentinel back in his orange colors as well! Amazing, keep it up IDW, let's hope Chaos and this Galvatron business picks up just as nicely.
