A never-before-seen Dr. Seuss story titled What Pet Should I Get? is being published on July 28th, more than 20 year's after the author's death. The manuscript and illustrations for the book were found in a box in Theodor Geisel / Dr. Seuss' home in 2013 by his widow Audrey Geisel.

The book features the same brother and sister that appear in One Fish Two Fish Red Fish Blue Fish, and although plot details are thin on the ground, publishers Random House Children's Books say that the new title will feature (spoiler alert!) a decision-marking process involving pets. "The tale captures a classic childhood moment — choosing a pet — and uses it to illuminate a life lesson: that it is hard to make up your mind, but sometimes you just have to do it!"

And there's more good news for Dr. Seuss fans — enough material for two more books was reportedly found in the same box, and Random House say they are working on getting them ready for publication too. Meanwhile, What Pet Should I Get? is already available for pre-order for $17.99.
