Description: The Treehouse series—a global bestseller with over 7 million copies sold!!! Ever since The 13-Storey Treehouse was first introduced in Korea in 2015, readers have responded with excitement to each new installment, as the treehouse grows by 13 storeys with every thrilling new adventure. The publisher has been flooded with requests for the next book, and even before release, pre-orders alone have propelled each title to the #1 spot in the children's category on major Korean online bookstores like Aladin, Yes24, and Interpark—and even onto the overall bestseller charts. In particular, The 91-Storey Treehouse shot up to #2 overall on Aladin and #3 overall on Yes24 as soon as pre-orders opened. The popularity of the Treehouse series isn't limited to Korea. Published in 25 countries around the world—including the US, Japan, France, and Germany—it has won the hearts of young readers everywhere. Publishers Weekly recently reported on the series' rapid sales growth in the US market, along with news of a two-week author tour and a special event featuring Jeff Kinney of Diary of a Wimpy Kid fame. The Treehouse series has even been adapted into a stage play, enjoying huge success in Australia and now preparing for performances in the US as well. In 2018, following The 91-Storey Treehouse, Treehouse FUN BOOK 2 is set to meet Korean readers, while Treehouse FUN BOOK 3 is scheduled for release in Australia around March. With The 104-Storey Treehouse and The 117-Storey Treehouse both recently confirmed, expectations are higher than ever for the series' continued success. ▣ About This Book The easiest job in the world—or maybe the hardest: babysitting! In The 91-Storey Treehouse, we find the tent of fortune-teller Mrs. Know-It-All (who was already predicted to appear back in The 78-Storey Treehouse), a deserted island, a trophy room, and a giant red button. While Andy and Terry are arguing over whether to press the button, they ask Mrs. Know-It-All for advice—and she predicts nothing but 'doom,' along with the two of them babysitting some kids. Just then, publisher Mr. Big Nose shows up, dumps Alice, Albert, and a baby on them, and demands a new manuscript and the return of the children by tomorrow. Manuscript troubles aside, can Andy and Terry manage to keep track of children who vanish the instant you take your eyes off them? Readers eager to find out will find it just as hard to look away from the book! Who will write The 91-Storey Treehouse now? Chasing after the missing kids leads to one wild mishap after another—getting sucked into a whirlpool, sinking 20,000 leagues under the sea, stranded on a desert island, and tangled in a giant spiderweb, with barely a moment to catch their breath. To make matters worse, Andy and Terry's heads have gone completely empty, leaving the manuscript stuck in place. At this rate, there might be no 91-Storey Treehouse at all! But since a Treehouse book has never failed to come out on time, Jill steps in for Andy, and a suddenly super-smart Andy—now going by Andrew—starts writing instead. Of course, Jill keeps getting sidetracked talking about her favorite animals, while brainy Andrew rattles on with words so complicated it's as if he swallowed an entire dictionary. So who will actually manage to finish The 91-Storey Treehouse? And will it even turn out right? Readers will want to grab Mrs. Know-It-All and demand answers, but between the giggles and the suspense, they won't be able to stop turning the pages. The one thing know-it-all Mrs. Know-It-All didn't know If you want to know something, all you have to do is read a book. Any book at all! As it turns out, the one who emptied out Andy and Terry's heads was Mrs. Know-It-All herself—all because she wanted to know everything in the world. But even someone who prided herself on knowing everything didn't know one simple truth: if you want to learn something, you just need to read a book. Just as Jill and the kids filled Andy and Terry's empty heads by reading to them! It doesn't matter whether it's a nonfiction book, a novel, or a picture book. As super-smart Andy once said, 'knowledge is power'—but when it comes to pushing past the limits of what you know and learn, nothing matters more than imagination. And no book is packed with more imagination than the Treehouse series. Sadly, though, Mrs. Know-It-All never gets to learn this truth herself, because Mr. Big Nose's nose explodes with rage at her before she can find out—and she disappears! With the 104th storey just around the corner, there's no stopping now!
