Is there a second Stuart Little book?

Yes, there is a second Stuart Little book! It's called "Stuart Little" and was written by E.B. White. It is the sequel to the first book, also titled "Stuart Little."

While the title might seem confusing, the first book is a stand-alone novel, while the second book is a continuation of Stuart's adventures.

It's important to note that there's also a movie series based on the books. The first movie is titled "Stuart Little," and the second movie is called "Stuart Little 2." While the movies are loosely based on the books, they have their own distinct storylines and characters.
