Margaret is a sweet girl who always does what she is told. When she turns 8, she cannot wait to finally go to her friend Mary’s house by herself. On the way, a twig gets caught in her wheelchair tire, and she falls over, trying to stop herself by pushing on a tree, but the tree is not hard as she expected, and she gets sucked into a whole other world.
Margaret and The Secret Soft Tree is written by Jaime Lee Mann. Check out her Legend of Rhyme series at https://legendofrhyme.com/. This wonderful series is suitable for middle-school-aged kids.
