I've been on a quest for some quality middle school literature. The new series by Patti Wheeler and Keith Hemstreet is a treasure of educational fiction. "Travels with Gannon & Wyatt" is an adventure/travel series where twin brothers journal about their global expeditions.
In the first book, Botswana, Gannon & Wyatt tell of their adventures in the African Savannah trying to stop a poacher and save an injured lioness.
While exploring for a "Spirit Bear" in the second book, Great Bear Rainforest, the boys go in search of the captain, a famous scientist and their parents who all go missing in the protected rainforest.
This series is great for 4th-8th graders. The books have short chapters, designed like journal entries that reluctant readers won't mind. Advanced readers will enjoy the animal and geography facts along with the suspense and adventure in both stories.
* I received these books from the publisher, Greenleaf Book Group Press through NetGalley.com in exchange for my honest opinion.
