"I'll never forget what we did."
"Save the world?" Dak asked.
"Yep, save the world. And I'm glad it was with you."
We have reached the end - seemingly, anyway, but more about that later on. In this book, Dak, Sera and Riq tackle the Prime Break, the very first one, and they travel back to Ancient Greece to meet Aristotle and Alexander the Great.
Now, don't get me wrong, that's pretty cool, but somehow you would expect just a bit more. There's only so much you can do in 190 pages, of course, but even then it looks like Dashner and the team at Scholastic could have made the stakes a bit higher at times. It never reaches its full strength, or at least that's how it feels after six books full of time travel. You could do more with it, but that's not really visible in The Iron Empire and feels like a missed opportunity.
The characters, however, have grown a lot over the course of the series, and it's nice to see how they've come together as well.
Originally, Infinity Ring was supposed to comprise seven books, but for some reason they decided to add an extra eighth one. It's... weird - I'll talk about that in my review on Book 8 - but I just want to say here that it's clear they could've easily dropped the book. It's only here, in Book 7, really, that they set the pieces just so that a few final questions and openings remain. If they'd dropped those, the series would have ended completely here - and honestly, you should just stop reading after Book 7 too...
