I got this book early because my friend lent me her ARC and I will forever be grateful.
I'm gonna be as spoiler-free as I can because I know this book isn't technically out yet, but I'm gonna mention some spoilers towards the end, so just a heads up.
A lot of spin-offs usually feel unnecessary. Most of the time, you can tell that a spin-off is something the creator just half-assedly threw together so they could make more money, and was totally irrelevant to the original story. But I didn't feel that way about Monster at all.
Monster takes place about four years after the dome surrounding Perdido Beach has fallen down. The main protagonist, Shade Darby, lost her mother in the aftermath of the dome falling down. Her father is an important scientist who is investigating dangerous meteorites that are supposed to crash to Earth. These meteorites are connected to the radiation that originated the FAYZ, and consuming part of these meteorites can physically alter one's body and turn them into a dangerous weapon. Shade knows that dangerous people will try to get a hold of these meteorites and turn themselves into monsters. Feeling responsible for her mother's death four years prior, and wanting to seek revenge, Shade gets a hold of part of the meteorite, which turns her into a creature with the ability to run faster than light speed. With the help of her friend Cruz and her ex-boyfriend Malik, Shade begins to travel across the country in an attempt to stop the other monsters that have been unleashed on the world, and tries to become a hero. The book also features Dekka, one of the characters from the original Gone series, who has been recruited by the government to help stop the monsters that these meteorites have created.
Michael Grant did a great job of writing a brand new story focused on new characters, whilst still intertwining elements from the original series. This story clearly had a new plot and new characters, yet there were still references to other characters fro the original series throughout the book. The plot was also very interesting and clever. Basically, the entire book was about discovering that the crazy things that happened in the FAYZ didn't just happen because of the dome; crazy things were now happening all throughout the world. The government also played a significant role in this book, too, which was interesting because it wasn't something we saw in the original series.
The Gone series had a lot of great characters, and so did Monster. Obviously, it was great to see Dekka again, this time serving a lead role in the book. Dekka was the only character that would have fit in a main role in this spin-off, anyway -- everyone else's stories have already been told completely, but I felt like there was more potential for Dekka in the original series, and she definitely fulfilled that in Monster.
I also liked a lot of the other characters, too. My favorite was probably Malik; I really enjoyed his relationship with both Shade and Cruz. I also really loved, Armo, too...I thought he was kind of funny, and I really loved his dynamic with Dekka. Cruz was also a favorite of mine, and she was probably one of the more interesting characters of the book. The only character that I wasn't totally sold on was Shade. I want to like her, but I'm not sure if I do, yet. She was kind of cool, but she also got her friends into trouble a lot, and never really thought much about the consequences of her actions.
The amount of diversity we had in this book was awesome, also. Obviously, we already had Dekka, who's a black lesbian (and who I really hope finds a nice girl by the end of the series because I want her to be happy.) Malik, another main character in the book, was black. And Cruz was Latino, and was also trans/non-binary, which was really cool, because I've never read a book that featured a non-binary person, or even a trans person, come to think of it. Also, most, if not all, of the villains in this story were entitled white men, which is how it works in real life, anyway.
Honestly, though, the most exciting parts of this book were the references to the original Gone series. Any time they mentioned a plot point I got really excited and any time a character was even mentioned, I screamed out loud. There are a few characters (other than Dekka) who even make appearances in the story. There was one scene in particular that I really, really, REALLY loved, but I don't want to reveal anything about it. Just know it was good. Another great scene was the very last scene in the book, which I saw coming, but STILL had me screaming and has me INFINITELY excited for the next book.
[SPOILERS]
However, there were a few things about this book that disappointed me, and all of those things are pretty spoiler-y, so maybe avoid this section of the review.
Something that personally disappointed me is that my favorite character from the original series, Quinn, wasn't mentioned at all throughout the book, even though almost every other character was mentioned at least in passing. There were also a couple of unanswered questions I had at the end of Light (what happened to Toto the Truth Teller, did Lana and Sanjit stay together) that I was hoping would be answered in this book, but no such luck. There were also a few characters that were mentioned in passing, but it wasn't revealed what they were up to four years after the FAYZ, which I kind of wanted a few hints about. But I know there will be more books (I think two more?) so hopefully the characters that were left unmentioned will appear later, and we'll get answers to some of the questions left unanswered.
Probably the thing I liked the least about this book, though, and this is a BIG SPOILER, is that Drake makes a return. He doesn't have a huge role or anything, but come on. I spent SIX WHOLE BOOKS hating Drake Merwin with every fiber of my being, and the countdown in Light was even counting down to his death, yet it turns out he's not even actually dead? Honestly, it felt like a huge cop out and I was kind of pissed. I would've preferred that Grant use new villains, or if he was going to bring a villain back, maybe the Gaiaphage or something, but not DRAKE.
[END SPOILERS]
But honestly, that was the only major issue I had with the book. I definitely recommend this book to anyone who loved the Gone series, and to those who have never read the Gone series, what the hell are you doing with your life. This book was great, and I'm so excited for more books. When I first read the Gone series, I was reading it when all of the books were already out, which meant I never had to wait between one book and the next. So waiting for the next book after Monster feels kind of weird, but I really feel like it'll be worth the wait.
