this was the most incredibly awesome crossover book ever!!! I really hope some characters from the locker nine series.. I hope we get to see them again maybe in another crossover book maybe we can see them in The Borrowed World Series. or even maybe The Mad Mick series. maybe they can do something that’s never been done. and do a triple crossover & have The Locker Nine Series, The Borrowed World Series & The Mad Mick Series. Even though The Locker Nine Series has ended they can still bring back characters to continue there story. I don’t feel like The Locker Nine Series got enough of a chance I love it that series is wonderful!! I feel people need to give that book series another try. I think they’ll like it just as much as the other Franklin Horton looks. I am also a big fan of The Ways Of Dan Series That is an amazing series. Ooooh maybe they could do a crossover book With The Ways Of Dan and another one of Franklin Horton’s books. but sorry about naming all these books in this comments to give you a review on this audiobook. this book was amazing I couldn’t ask for this book to get any better. it did some great tying up some loose ends. and also exploring the possibility of some newer things that could happen later on maybe another series spin-off or something like maybe we’ll see the Mad Micks daughter in her own series that would be awesome!! oh man now I’m thinking about that that would be great. I just love her character her character is just so spunky and she can be so funny in one moment, then without warning she can be totally kicking your butt in the next!! she is one kick ass woman pardon of my language. I never cuss usually I apologize. I just couldn’t help it she is so awesome and the writer Franklin Horton he is amazing author. Don’t miss this book don’t miss the whole series. if you are just joining the series go back to the very beginning. and also check out all the other series by Franklin Horton he’s a master writer. Let me tell you something his books don’t ever get boring. you will never find yourself being able to go to sleep while you listen to one of his books. His books are always keeping me on the edge of my seat I like the fact that there is some cuss words in the book but not that much. the books are a lot more family-friendly than I thought when I first started listening to them. but there’s a few bad words in the books but only because that’s realistic about what would be going on at that time in the world. people would be talking like the way they were in the book quite realistically. so I don’t get mad at this bad words because let’s face it the is people out there that talk like that all the time. but I love that there’s not too much like I don’t feel like that’s all I’m hearing. I’m really able to sink myself into a book and immerse myself in an imaginary world of a series. I just close my eyes and just imagine all the characters as I listen and it really helps to picture the world around each character and how they would look in the world that they’re in during that series. I love that I can use my imagination like I did when I was a kid as I listen to these great books. and Kevin Pierce is the best choice of a narrator!!, He Is the best narrator I’ve ever heard and I hope that Kevin Pierce continues to do more Franklin Horton books in the future.
