Initial Impressions 1/31/15: This was just so much fun! I loved how there was actually a lot of action & plot even for a short novella. It was a great transition from Steelheart to Firefight and although it's not NECESSARY to read before Firefight, it is referenced so it's very helpful! And if you're enjoying this series, you should read it anyway! 
 Full review originally posted HERE on The Book Addict's Guide 3/7/15: MITOSIS was a really fun short story! I know not everyone is a fan of novellas and for STEELHEART fans who are in the same boat, you don't NEED to read it but you may WANT to read it! Firstly because it's Sanderson and it's just plain fun, but also because the novella does set up a few points for FIREFIGHT. 
 MITOSIS is a quick in-between story to bridge the gap between STEELHEART and FIREFIGHT and the focus is more on David and less on the Reckoners as a team. They're still working together but not all of the characters appear on scene, so to speak. It's a quick hunt to take down another Epic and this one happens to be important for FIREFIGHT because he brings up a few good ideas and points when the characters start to theorize some more. Obviously I won't go into the details, but this is also one of the many reasons why I'm encouraging you to read the novella! I think the information comes in handy and I think it's easier to read in MITOSIS first! 
 Other than that, the formula sort of follows suit from STEELHEART -- David is nerdy and funny (sorry, David. You are a nerd), Epics are still terrorizing, the Reckoners are awesome. I don't want to say TOO much more about it because the novella isn't incredibly long but I had so much fun listening to it and it made me even more exited for FIREFIGHT -- so much that I had to start it right away! (Seems to be a trend with me and Sanderson books.)
