Mary Pope Osborne, author of The Magic Treehouse series, returns to Houston to celebrate the publication of the 43rd Magic Treehouse book, Leprechaun in Late Winter.  Mary’s sister, Natalie Pope Boyce, the author of the nonfiction companion research guide, Leprechauns and Irish Folklore, will also be here.  To learn more about Mary, visit her website. The Magic Treehouse series follows Jack and his kid sister Annie as they find themselves traveling to a variety of places and times.  It’s a great series for emerging readers, introducing them to characters they begin to regard as friends and wish to visit again and again.  In Leprechaun in Late Winter, Annie and Jack  find themselves in the Ireland of 1862, equipped only with a magic whistle and the charge to convince an unhappy young girl that she has much to give to the cultural life of Ireland.   As we expect a large crowd, we will hold this event at Westchester Academy, 901 Yorkchester, in Houston.  There will be a brief presentation followed by the opportunity to meet the authors. Instead of a traditional signing, the authors will stamp rather than sign their books.   In order to get a signing line ticket to meet the authors, you must purchase Leprechaun in Late Winter from Blue Willow Bookshop.  Signing line tickets are issued in order of purchase.  In addition, you may bring two books from home to be stamped. No flash photography will be allowed at the event.
