The Experiment is an absolutely gripping, thought-provoking science-fiction adventure that took me on a heart-racing journey of discovery that kept me utterly enthralled.

Eleven-year-old Nathan has been keeping a secret his whole life, an incredible secret that is in danger of being exposed following something that happens to him on his family’s vacation in Florida. In order to stop his secret being revealed, Nathan must return to the Wagon, a spaceship from the planet Kast, his home world. Nathan has grown up believing that he is part of an experiment to ascertain whether the Kast can permanently maintain human form on Earth but what has happened in Florida has thrown doubt on its success …

When Nathan is recalled to the Wagon, it is with the knowledge that other members of his group, who he has spoken to virtually each year, have begun to disappear, including close friend Izzy with whom he has been communicating without his parents’ knowledge. Could the experiment have failed and will be have to leave Earth?

And so begins an absolutely riveting, action-packed adventure as Nathan and his parents are brought to the Wagon. When he meets some old friends onboard the mothership, it is not long before Nathan begins to question the nature of the experiment which has been such a part of his identity. Could Hester, who controls the ship, have been keeping the truth about the true purpose of the experiment from its participants? Can he protect those he loves from the egocentricity of someone intent on the success of the experiment, no matter the consequences? And, what will he learn about himself and what he has been taught to believe about why he is on Earth?

This really is the most compelling, thought-provoking read which I absolutely could not put down and read in a single sitting, helped by the short chapters which kept me eagerly turning pages. I really liked that the story is structured into six parts which gives the reader both an insight into the ship’s journey towards take-off, giving a sense of urgency and expectation, and a focus for what the characters will experience.

I don’t want to say too much for fear of spoilers but I found this an incredibly thought-provoking read as it delves into the human experience, interactions and relationships, self-identity and how self-concept can be affected both positively and negatively by others.

I absolutely adored the strong friendship between Nathan and his best friend, Victor with each wanting to support and protect the other, showing real courage in doing so. I loved how accepting Victor is when Nathan reveals the truth about himself, and loved that he finds joy in the ordinariness and comfort of Victor and his family. Whilst Nathan clearly adores his mum and dad, he is aware that his is not a ‘normal’ family life with his life being monitored and recorded by his mum so he enjoys the normalcy he feels through his friendships and school life. There is someone else who shows Nathan incredible kindness, friendship and understanding – but I will let the reader discover that wonderful someone for themselves!

A thought-provoking, fast-paced, page-turner, full of twists and turns, perfect for readers of 9+.

Thank you to Jade at Anderson Press for sending me a copy of this book in exchange for my honest opinion.
