This short story focuses on the gap in Mark's story and what happened to him between the Arizona base incident and The Revenge of Seven. I enjoyed the story, but not as much as the first short story about Mark. With the first short story, you really just learned so much about Mark and he changed so much related to what was happening; however, in this story, Mark didn't really grow, it was just a continuation. The best part of this story was finally getting to me Guard. I am super excited to see how Guard is going to be integrated into the new book and how he/she will help up the Loriens. If you love the I am Number 4 series, I would say this is a must read.
