An author reminisces on her life and her work.After 30 years of writing the Magic Tree House series, Osborne collects some of the books' core values and lessons and makes connections to moments in her own life, whether formative or small. As a child in a military family, she moved frequently and often relied on her siblings, her imagination, and nature for reliable amusement. The 10 chapters each present a different theme, such as the importance of compassion, the magic of a good book, honoring heroes, and the warning to "Be Daring, but Not Foolish." Each short chapter presents particular maxims, some of which are more profound than others ("Look outside yourself to find unexpected treasure all around you" versus "Love dogs. Start now"), but they are always sincere. Prefacing each of Osborne's reminisces are selections from various series installments that relate to the theme at hand. However, this scrapbook memoir is only loosely tied together, and readers will probably get only minor satisfaction from it unless they are great fans of the series. Two-toned pictures by the original series illustrator, Murdocca, are interspersed throughout; children depicted present White. Bookending the text are notes from the author on why she decided to write this work as well as the moment of inspiration for the series. Also included are some of Osborne's family photographs.Strictly for the author's devotees. (Nonfiction. 7-12)
