Iron Man, Volume 3: The Secret Origin of Tony Stark, Book 2

It's actually interesting enough to read but the execution is very poor at some parts.

Overall this one is good, especially it talks about Tony Stark's secret origin and his relationship with his father

Ehh... like, I get that they needed to put Tony Stark in space to tie him in with Guardians of the Galaxy, but ultimately I just didn't care that much about this. I like Tony best when he's interacting with people, not stuck in space with robots. And the ending felt like a fakeout. But I'm glad Tony's back on earth.
