The Experiment by Rebecca Stead





Nathan and his parents know they are actually aliens living on Earth as a part of an experiment (yes that is the title). Nathan lives in New York and to some extent he lives like a normal kid - going to school, using his phone to talk to his friend, enjoying sleepovers, and reading his favourite comic - Calvin and Hobbes. But early on in the story a few things seem strange. He has to brush his teeth five times a day including at school with a special pink paste, his mother documents all his food and Nathan himself is weighed and measured regularly. Nathan also has some friends who live in different parts of America - Izzy (Isabel) from Illinois; Nina from New Mexico; Annie from Alabama; Leo from Louisiana; and Miriam from Missouri. Are you noticing a pattern here? And then we read that some kids have disappeared. 

The action moves with a swift pace as we watch a count down at the start of each section - Lift off minus eight days; Lift off minus seven days; Lift off minus six days; Lift off minus ten hours; Lift off minus ten minutes; Fate and Happiness. You should also stop and notice the chapter headings.

There is a moment in this book on page 255 where I found myself screaming at Rebecca Stead. I was sure Nathan was either going to die or be whisked off to Kast. I read The Experiment late into the night and again around 3am and then this morning I finished it off. This is a long book (207 pages of smallish print) but readers aged 9+ with reading stamina are sure to find themselves quickly hooked into the story. 

I want to mention a couple of things that I loved and that are quite different in this story - Nathan does not hide things from his parents - as a group they feel like a team and all of them want to discover the truth about The Kast and Hester and also find out why Nathan now has a tail (he names her Tuck) - you can see this on the cover. The other aspect of this story that was very different from other books about power and control came at the end (spoiler alert) when Hester is taken away on the spaceship and not punished and it seems she might have some sort of odd, but nevertheless happy, ending. 

Publisher blurb: Nathan never understood what was ‘fun’ about secrets, probably because he’s always had to keep a very big one, even from his best friend, Victor. Although he appears to be a typical grade-six kid, Nathan learned at an early age that his family is from another planet, and he’s part of an experiment to work out how to behave like a human and blend in. But the experiment suddenly seems to be going wrong. Some of the other 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. Can he, Victor and Izzy uncover the truth? The Experiment is a fast-paced adventure—with aliens—that asks universal questions about how we figure out who we want to be, whether it’s ever too late to change, and the importance of friendship.

Betsy Bird has penned a very detailed review of The Experiment (but be warned it is filled with spoilers). She links this book with Charlotte's Web, and like my experience of reading this book, that idea has also blown my mind! Betsy recommends reading her review AFTER reading The Experiment - and I whole heartly agree. Also DO NOT SKIP to the end of The Experiment - please let the story unfold and know you can trust Rebecca Stead that there will be answers to all of your (and Nathan's) questions.

Strong character development, like the complicated backstory of a villain, brings further depth, as do the believably strong relationships, including Nathan’s unbreakable friendship with Victor. Stead’s creativity shines here, from Nathan’s unusual tail to later plot twists and turns (not to mention the tattletale, alien-enhanced cat). Anyone who enjoys Stead’s writing, along with sci-fi lovers and even superhero fans will easily devour this latest offering, staying up late under the covers with flashlight in hand to read just one more chapter. Bulletin of the Center for Children's Books

In this video Rebecca Stead talks about her books including The Experiment and Rebecca is interviewed by Betsy Bird. Here is the Reading Time review (but I disagree with the idea that this is 'tongue in cheek') Here is the review from Ms Yingling.

A few years ago I penned a post about Science Fiction books for young readers. For myself I well remember reading Trillions by Nicholas Fisk and The World Eater by Robert Swindells and having my mind blown because that's what Science Fiction can do - and now that has happened again with The Experiment - my mind is officially blown again. But by far the best books to compare with The Experiment are Halfway Across the Galaxy and Turn Left by Robin Klein and Edsel Grizzler and the Voyage to Verdana by James Roy. Sorry, these are both old books now so you will have to hunt in a library.




Here are the teachers notes

Galax Arena by Gillian Rubinstein (1992) is a far more sinister story but it is also a book that I thought of after reading The Experiment. 



And try to find these too:

I think parts of The Experiment will also linger with me because earlier this week I re-read The Giver by Lois Lowry which, as you probably know, also talks about control and manipulation.
