The Experiment - by Rebecca Stead (Hardcover)

About the Book

Eleven-year-old Nathan and his parents have a mission to blend in with humans on Earth, but when Nathan starts growing a tail, he begins to question the true purpose of their alien experiment.

Book Synopsis

Read the highly anticipated novel that Betsy Bird calls "A great, grand endeavor that, by all rights, should be around for years and years to come."

From the Newbery Medalist and national-bestselling author Rebecca Stead, here is a bold story that will appeal to fans of A Wrinkle in Time and The First State of Being.

Nathan wants to help his people, but first he has to figure out who they are...

Nathan never understood what was "fun" about secrets, probably because he's always had to keep a very big one.

Although he appears to be a typical sixth-grader (with parents, homework and a best friend, Victor), Nathan learned at an early age that his family is from another planet. Now, their time on Earth may be coming to an end.

Nathan, his parents and nine other families are part of an experiment that suddenly seems to be going wrong. Some of the experimenters, including Nathan's first crush, Izzy, are disappearing without a word. After his family is called back to the mothership, Nathan begins to question everything he's been taught to believe about who he is and why he's on Earth.

The Experiment is a fast-paced coming-of-age novel that asks universal questions about how we figure out who we want to be, and whether it's ever too late to change.
