Joe's parents are spies. He has only just found out about this and it turns out his parents are in danger. As a disguise, Joe takes the name Josephine and has to become a girl – much to his disgust. Then he notices some unusual goings on and turns into a spy himself...

My favourite character in the book is Sam because she is very cool and is very surprising to read about. I loved the part when Joe finds out he has to pose as a girl for his disguise because it was really funny!

I would recommend this book to any reader aged 7 and above because it is really cool and funny and I have to give it 5/5 stars because I liked it so much!
