Honestly, I never did reviews on here because I'm not the best writer in the world but GOSH THIS BOOK WAS SO GREAT IT DESERVES A REVIEW. 
 My god. Where do I even begin with this book? I read a number of great books these past few months, but this one just topped them all. A friend of mine actually recommended this to me a few years ago but I never picked it up until now. Now, I just wish I would have gotten to it sooner because it was such a great experience of a book!! 
 This is the first book I've ever read by Alison Goodman, and I wasn't even halfway through the book when I declared myself a fan of this author. I give this lady a million rounds of applauses for creating such an amazing world based on Asian history and culture, and delivering the whole story perfectly with her writing. I will admit that the pacing in this book seemed slower than the most recent books I've been picking up. However, there was not one moment where I was ever bored or thought of wanting to put this book down because there was so much detail put into every sentence and paragraph. Alison Goodman was able to create her world through her words and keep me so intrigue through every single word I read on the page. 
 The story itself about a girl masquerading as a boy wasn't anything all too new, but the way it was all laid out right in front of me while I was reading just drew me in and I was absorbed in it completely the whole way through. The book had pretty much no romance in the main story whatsoever, which I kind of like. Although I am one to enjoy a properly delivered romance in the books I read and I am not exactly bothered by romance, I feel like this story really didn't need any. Otherwise, it would have been a bit hard to fit everything in and explain all that was needed to be said without making the book longer than it already is. 
 I really want to mention about the characters in this, because the characters in this book were fantastic. They were one of the reasons why I was so drawn into the story. The main protagonist, Eona, was especially one that kept me intrigued. I can honestly say that she is now one of my favourite book protagonists of all time. She was such a strong, determined, and complex character who does have her fair share of flaws. There were times when I was bothered by her stubbornness and some of the decisions that she would make, but that did not stop me from wanting to keep rooting for her until the end. Eona was one of the most interesting characters I've ever read in YA fiction and she'll forever be one of my faves. 
 As for the supporting/side characters, they were all just as fantastic and they each had such complex backstories and personalities for side characters. Some of my favourites included Rilla and Ryko, though I honestly loved almost every single one of the side characters. The villain of this story was..........I had a like/strong hatred relationship with the main villain. I liked him because he was such a complex and powerful villain who knew what he wanted and exactly how to do it. However, because of that I of course had a strong hatred for him ((view spoiler)[And when he was being all up in Eona and kissing her and stuff that was all just.....BLECH. I cringe at those scenes. That sun drug really just threw all sanity out the window for that dude. (hide spoiler)]). He is still a great villain nonetheless and possibly one of my favourite villains in YA fiction. 
 Eon is now probably one of my, if not THE, favourite books of all time and will probably be up there as well with my favourite series of all time. (Not sure whether I'll put it as my #1 favourite series of all time yet, since at the moment when I am writing this I have only read Eon and have not picked up Eona yet). I absolutely cannot wait to grab myself a copy of the sequel Eona and get to reading that! I need it like.....NOW. RIGHT NOW. I am also looking forward to someday picking up other works by Alison Goodman, as this book alone has gotten her listed down as one of my top favourite authors of all time now!
