Projects like this are why I love Kickstarter. The Girl Who Would Be King is a fun, well-written gem of a book, and if traditional publishers had the final word, it never would have seen the light of day. This book is admittedly difficult to classify-- it's a YA book that is somewhat longer and more "literary" than most YA books, and it also contains more sex, violence, and sci-fi elements than are normally seen in YA literature. Instead of brooding vampires, jealous werewolves, or teens struggling to survive the zombie apocalypse, this book features female superheroes doing both normal and super-heroic things. I can see why publishers were hesitant to take on this challenge (Established genre conventions! Marketing difficulties! Angry parents!), but that doesn't make it any less disappointing that they chickened out. At any rate, it's their loss and the Kickstarter backers' gain. In exchange for my pledge, I received an ebook, a print copy, and the satisfaction of supporting the author directly. Take that, traditional publishing! 
 I read a lot of YA books, some for pleasure and some for work (I'm a librarian). In my opinion, the best teen books are difficult to categorize specifically because they don't fit the mold. Looking out on the teen lit publishing landscape, I see a lot of Twilight/Hunger Games/Percy Jackson knockoffs. They may follow the genre conventions, and they probably sell fairly well, but there's nothing unique or original about them. The Girl Who Would Be King is a totally original concept, and without giving anything specific away about the ending, this could EASILY be the first book in a series (although I would settle for a sequel). However, traditional publishers thought that we needed another vampire romance or dystopian trilogy more than we needed this book. I strongly disagree, and I suspect you will too. I highly recommend this book for mature teens, fans of strong female characters, comic book enthusiasts, and anyone who enjoys solid YA lit that doesn't follow all the rules.
