An unpublished Dr. Seuss manuscript was found in a box of sketches left by Theodor Seuss Geisel. The book, “What pet should I get?” is scheduled for a Jul. 28 release.

Geisel, known to the world as Dr. Seuss, died in 1991 at age 87. The box was discovered when his widow, Audrey Geisel, remodeled her house. After going missing again, it was rediscovered in 2013.

The sketches and text for “What pet should I get?” were nearly complete. Audrey called the discovery “undeniably special” but indicated that she wasn’t surprised.

“Ted always worked on multiple projects and started new things all the time — he was constantly drawing and coming up with ideas for new stories,” she said.

“We had no idea what we were in store for when Claudia notified us of the materials discovered in Ted’s home,” Susan Brandt, president of licensing and marketing for Dr. Seuss Enterprises, said. “Pages and pages of manuscripts and sketches were laid out on the big glass dining room table. It was truly a magical moment, and we immediately knew this was more than just a box of sketches.”

Random House Children’s Books, the publishing company for Seuss’s stories, said at least two more Dr. Seuss books are forthcoming.

Besides writing, R. McKinley loves reading (especially historical fiction and science books), playing piano and flute, being involved in politics and community, working out, enjoying nature, and hanging out with four wonderful cats.
