Author Testimonials

  • “Diane Landolf is one of the best children’s book editors in the world of children’s books. As editor of the Magic Tree House Fact Trackers she always made a book better with her insights, questions, and thoughtful guidance. The Magic Tree House team is immensely grateful for her years of brilliant work.”

    — Mary Pope Osborne, #1 New York Times bestselling author of the Magic Tree House series

  • “I feel extremely fortunate to have had Diane as my editor for the first four books in the Dragons in a Bag series. She's warm, responsive, efficient, but also flexible—she recognizes that authors (like editors) have a life beyond our books and Diane made accommodations when necessary. I always felt that Diane honored and genuinely tried to understand my vision; she shared her point of view but also respected mine and together we created a series that has enchanted thousands of young readers. I would absolutely recommend Diane as an editor—and would hire her myself for my next indie project.”

    — Zetta Elliott, author of Dragons in a Bag and series, an ALSC Notable Children’s Book and the 2021 Global Read Aloud

  • “How DARE you not hire *THE* Diane Landolf! Rectify your mistake immediately! . . . But seriously, your manuscript is in safe, careful, and capable hands with Diane.”

  • “As a first-time author, I was so fortunate to have Diane Landolf as my editor. Although I write for television and film, novel writing for middle schoolers took special attention to character exposition, and Diane guided me through. Now that LOVE DOUBLE DUTCH! has been optioned for a TV series, it's a testament to Diane's ability to bring out the best in a character-driven story. I am so grateful to her and can only hope we'll work together again.”

    —Doreen Spicer-Dannelly, author of Love Double Dutch!

  • “Diane Landolf was extremely helpful in guiding me to make the historical material in my novel accessible to both child and adult readers, without sacrificing historical accuracy. Working with her was a great experience!”

    —Karen Schwabach, author of The Hope Chest and Starting from Seneca Falls
