Sophie and Max Investigate a Wormhole

Through a shift in time and space, a beautiful young scientist is transformed into a Siamese cat. She is found by a kind old man who lives with a shaggy dog, Max. Deciding to keep the cat, Angelo names her Sophia after his favorite movie star, Sophia Loren. The cat is determined to return to her former life as a human, and Max is only too happy to help-to get rid of her! In their adventures across space and time, in both animal and human forms, they overcome difficulties and learn the true meaning of friendship.
Antoinette Corum's novel Sophie and Max Investigate a Wormhole is not just the funny and fanciful fourth book in the series-it strives to portray certain scientific concepts accurately. Middle-grade readers and teens will enjoy and learn from it, just as generations before have loved Charlotte's Web, A Wrinkle in Time, and the Magic Tree House books.
