The perfect companion book to the New York Times bestselling I Am Number Four series!

I Am Number Four: The Lost Files: Rebel Allies is the fourth collection of action-packed novellas from Pittacus Lore. Initially published separately as digital originals, these three stories are now together in one print volume.

Lost Files: #10: The Fugitive follows Mark James as he tries to track down Sarah Hart, evade the Mogadorians and the FBI, and discover the identity of the mysterious blogger he knows only as GUARD.

Lost Files: #11: The Navigator reveals the truth about the crew of the two Loric spaceships who escaped to Earth and shows what happened to the pilots after they arrived and parted ways with the Garde.

Lost Files: #12: The Guard tells the story of the hacker who has been aiding the Lorien survivors from the shadows for years. She's determined to defeat the Mogs—and she just found her secret weapon.

You know the truth about the Mogadorians' invasion of Earth and the Garde who will do anything to defeat them—yet there is still so much to learn. The stories in Rebel Allies will help you get the answers you seek, but they will not help you stop the coming war. Only the Garde can save our planet. But they are not alone. . . .

The I Am Number Four series is perfect for fans of science fiction adventures like the Fifth Wave series by Rick Yancey and the Beautiful Minds series by Alexandra Bracken.

I finally got some more things answered in this one because there was so many things that didn't make sense in two of the books but finally after reading this one it all makes sense now.


The Fugitive: 3.5/5 stars
The Navigator: 4.5/5 stars
The Guard: 4/5 stars


Plot: This novella takes place during the main series and we first see Mark who is on the run after leaving John, Six, Sam, Sarah and Bernie. I wanted to know more about Mark's journey because he changes so much from the first book when we see him as a jock who runs the high school because hes that popular. He even states that he had it all from having a girlfriend to having his future figured out for him to now being on the run from the government, this character goes through one of the biggest changes in the series. However in 'The Fugitive' we see him on the run and moving from place to place trying to find this person who is helping him and he does ultimately finds who it is.


We are first introduced to Lexa in the main series and i have always wanted to know what she got up to before we meet her and the last two novellas in this one really cleared it up. Lexa is a very smart person and it was interesting to see how she was silently helping on the sidelines without being noticed and came out of hiding when she was ready.


as with most novellas and this one isn't any different i recommend you reading the series before you pick up this one especially because this one picks up right in the middle of the main series so you will get spoiled if you read this one first.

Finally, some much-needed answers after The Revenge of Seven and Hidden Enemy! Chief among them - who is GUARD? The answer is, thankfully, revealed in the first novella of this collection, while the remaining two are devoted to GUARD's backstory. And what a backstory it is. Move over, Marina, Nine, Six, Sam...I've got a new favorite character in this series, and if GUARD doesn't show up in The Fate of Ten, I'll be sorely, sorely disappointed.

It's been awhile since I've been this engrossed in a book. It's taking me awhile to get through this series, but every time I pick up one of the books, I wonder why I keep taking such long breaks. This book was packed full of incredible action and amazingly intricate plot (and it was only a compilation of novellas!). I love that these novellas are integral parts to the main story, and that we learn so much in them that we didn't know before. I can't wait to see how Lexa .

This book was so great. I read the I am Number Four series years ago, but this book took me right back to the fantastic world and story of the series. It made me want to read the whole series all over again.

The following will contain spoilers.

At first, it took me a while to get back into the story, because it had been such a long time since I read the other books. I'm not sure if I was less into the first part, which was Mark's perspective, or if it was just that I needed a little bit of time to get back into the story. As for the 2 other parts, both being stories told from Lexa's point of view, I was loving every single seconds of it. Being able to see Lexa's story before coming to Earth and seeing her evolution after arriving on Earth was really enjoyable. I loved her so much, she was such a badass.

Once again, I can only appreciate the quality of the writing of Pittacus Lore (James Frey).

This novel was very fun to read. I’m hoping to start the second one as soon as I can. Though I happened to have tons of time to read this book, it only took me a few days with how captivated the book kept me.
For the most part, the book was pretty mellow during the build up. Things like training, and everyday affairs keep a reader up to date, but the little tidbits inlaid in those tasks kept the pace steady. Those little bits of information did not always apply to the story immediately. There was one instance where the information didn’t make any sense until the end of the book. Unlike some books I've read, this didn't fizzle out halfway through and this kind of surprised me. I wasn’t anticipating how the book ended but that was a result of many smaller events that were almost insignificant to any normal person and that’s what made this book one of the better ones I've read.
Along with the general story line, the characterization was very vivid. I found little to no trouble in picturing the characters and their actions even though they were unearthly. Picturing him levitate tennis balls and sustaining a full body flame was pretty different but fun nonetheless.
The whole setting is mostly in a small and even during Halloween, it wasn't very hard to construct the whole town within my mind. I based most of it on a mixture of things with some of my knowledge of the area to really smooth things out. Where he was in the town really did affect what was happening, from training in his backyard to saving people from a burning building and the serenity of a morning run. I really liked how the author made it easy to picture everything. By far the best detail that made it easy to picture things was the modern time of the whole novel.
After my short, but great experience with this book, I would easily recommend it to anyone over the age of 12, and who is into the science fiction genre. The way the story is written makes it easy to follow and with some great twists, it keeps the attention of its readers.

What I really enjoy about this particular collection of novellas is that it truly brigdes gaps between the novels and fills out the background of some quite important characters.

The Fugitive: 5/5.
This is thr continuation of Mark’s story following Return to Paradise. His whole life has been turned upside down after the attack in IANF, but to his credit, he is taking it in stride. In fact he has evolved quite a bit as a character and while he might be focused on finding and saving Sarah as his goal, this only serves to fuel his willpower even more. And this story shows that while that initial motive might be selfish and small-minded, it guides his actions and helps him to not get overwhelmed by the magnitude of what he is doing- fighting against the Mogs and the FBI. This is the story that made me love Mark James and saw him evolve from selfish jock stereotype bully to something more.

The Navigator: 3/5.
This is the story of the Loric that wasn’t Cepan or Garde, but still went to Earth. The pilots who flew the chosen ship and the mysterious second ship with Ella and Crayton. It is also the set up for the next story, and as such I feel like it doesn’t stand Well on it’s own and while Lexa’s qualms about the Loric government are understandable, it seemed like her character was a bit of an afterthough - though as it turns out she’s highly important.

The Guard: 4/5.
The continued story of Lexa, computer genius extraordinaire and Intelligence collector. This is the story of how she works behind the scenes to protect the lives of the Garde as well as their secrets. I like how this story brings together Lexa, Mark and Sarah, but just as they finally met and become this awesome group of hackers, the invasion begins and everything goes to hell. It moves very fast and does some strange time jumps for the sake of story length, but ultimately I really like this story as this and the one before tells the story of the Loric who got kind of forgotten on Earth.

10 out of 10. What else is there to say? If you like the Lorien Legacies then you'll like all of the novellas. In some cases the novellas have been so good they give the main series a really close run for their money. I love these, they never disappoint.

I wrote a crap-ton of Reading Notes while I was reading this, so feel free to have a peak at them below this review. They might be a bit spoilery even though I marked the really spoilery ones, just a heads up.

This is a short little prequel that gives you some background information on Number Six, and whets your appetite for the soon-to-be-released sequel to I Am Number Four. The author has an engaging writing style, and if you liked I am Number Four you are going to eat this one up yet wanting a lot more. Which is why they released it a couple of weeks before the sequel. I'm ready, my wife is ready, and both of my kids are ready for the sequel and we all enjoyed this little prequel.

I am disappointed in the pricing at $3.99 - while the story is good, it only took about 20 minutes to read. However, the accountant in me knows why they did it but it was a little disappointing being so short. However, I guess four family members reading the same thing - at the same time - more than makes up for it.

Regardless, if you enjoyed the first book and are eagerly awaiting the sequel like we are, this will certainly set the stage.

General feelings: why was this so intriguing?

I mistook this for the first book in the series, and I jumped right in and was so confused! I had seen the movie before but did not recognize the first section, and I soon realized that this was not the first book. I kept going, thinking that the knowledge from the movie would help me. It did for a while, but then I got thrown head first into so much more than I was prepared for and I found it so entertaining!

I enjoy the mental gymnastics of learning on the fly, and I definitely had to do that without the context of the rest of the books. When I went back and read book one, it was much less entertaining because of all of the exposition.

Mark was enjoyable to follow, but I looooved getting the perspective of "Guard". Getting to witness the destruction of Lorien first hand, and watching her struggle to survive on her own was really heartbreaking.

I am looking forward to continuing with the rest of the series because of the enjoyment I got from this installment!

Another good book with three short stories. The Fugitive was about Mark surprisingly. Its about when he left his home to go track down Sarah and was talking to a person by the name of GUARD threw the Internet. Then in The Navigator it was about a girl names Lexa who was the driver of the second ship that left Lorien during the invasion! You learn what happened to the ship and the people and animals on it. I have to say it was the most interesting story out of the three. The last one, The Guard was about Lexa again and also Mark and Sarah all meeting up together! All three of these stories really connected to each other which I thought was really cool.

In this set of novellas we hear of Lexa, one of the Loric who is secretly helping the Garde behind the scenes as a computer warrior and expert hacker.
Both hers and Mark James story seem rather intertwined so this set deals mostly with their backstory, of how Lexa escaped to Earth as a pilot on one of the last Loric ships off Lorien and her subsequent struggle to stay underground and help the Garde and their cepans from afar and now her new human ally, Mark.

I really like these short stories, not only because they fill in the gaps of the story that aren't following Number four but also because the side characters are explored. Here we got to learn more about Mark, which made him a more likable character to me, and made him have more depth than what we saw in the main story line. Maybe he was stereotypical to begin with, but he really did grow quite a bit on his own.

I loved this book.. when I went to start it my husband said, “Oh wasn’t that a movie?” I was like well I’m not sure.. he was right.. this was such a high action book that I struggled with putting it down.. an alien.. a new town… a helper.. boys that don’t like you.. a dog that has joined your family.. it had a little of everything in it for you.. but it doesn’t stop there.. can’t wait to read the next in the series

I've read these novellas before, when I read the entire Lorien Legacies series, but I forgot how heartbreaking Lexa's backstory is. She's such a unique character with a completely different motivation and approach from the others. Also, Mark is one of my favorite characters -- excellent character development for him.

This trio of novella's answered several questions from previous books in the series. I quite enjoyed them, and, as always, I love Mark James to bits. Also really enjoyed getting to know who GUARD was and I love the addition of another badass female character. I'm quickly coming up on the last book in this series and I don't want it to end yet!

I find these novellas interesting as they helped to fill in the gap between books or helped to give some background on some characters. It did become a bit repetitive when Lexa's and Mark's stories come together, but overall a good read.

Everything seems to be adding up in this book, questions are finally getting answered. If you're reading this book I'm sure that you are far enough in the series that I don't have to convince you how great this series is.

I would say I enjoyed this, and it is important information that I want to have, but this isn’t one that I would read multiple times. It’s more of a background knowledge book. Yes it’s good to have the explanation of Lexa and how she came to their aid, but that’s about it.

Good insight onto the character of Lexa and some more in depth into Mark James life. Liked the stories.

Good amount of cursing, but overall okay for younger readers.

Good general backstory, wasn't super action packed though so I had a harder time getting through it.
