In her third adventure, Cookie finds mysteries everywhere - but can she solve them, and save the science show? Hurray, Cookie's Nani is coming to stay from Bangladesh! But she doesn't speak English and Cookie is the only one in the family who doesn't speak Bengali. Luckily, science-mad Cookie realises that her coding lessons at school might help her crack the language code and help her bond with Nani. Other mysteries are harder to solve, though - like, why is Jake's mum acting so weird? Who is the mystery gamer who keeps levelling-up in Cookie's computer game? And who is the Woodburn Hacker, who keeps posting teachers' secrets on the school website? Why does it look like it might be Cookie herself? Can Cookie solve these mysteries, clear her name and save the science show?

Cookie and the most Mysterious Mystery in the World is the third book in the fabulous Cookie series by Konnie Huq and it is absolutely brilliant!

Cookie finally gets to see her Nani who has come all the way from Bangladesh. However, Nani doesn't speak English and Cookie is the only member of her family that doesn't speak Bengali. Fortunately Cookie realises that her coding lessons from school might help her solve the communication problem and help her bond with Nani.

Written in the first person with Cookie as the narrator, the reader sees everything from Cookie’s point of view, making it very relatable for young readers, while helping adult readers understand how children sometimes misunderstand situations and other people. Cookie investigates a number of well executed, different mysteries in this book which fortunately for the reader, all come together at the end of the book.

This book is really easy to read with short chapters, The comic style illustrations, also by Huq, are simple but effective and break up the text for children who have not yet developed a good reading stamina. An ideal choice for fans of Diary of a Wimpy Kid and Tom Gates, and a great book for children and adults alike!

Cookie and the Most Mysterious Mystery in the World is the third instalment of the hilarious series by Konnie Huq. This book is full of mysteries waiting to be solved by Cookie and her friends, who seem to be connected to all of them. Through the character of Cookie, Konnie Huq is able to capture the essence of a child-like mind with all its endearing spirit and quirky outtakes.

At the beginning of the book, Cookie learns that her Nani is coming to visit from Bangladesh and although she cannot wait to see her; she is a little bit apprehensive because she doesn't know how to speak Bengali. Cookie also has a mystery to solve after catching Jake's mom getting out of a mysterious car very late at night.

Meanwhile, at school, Cookie is learning about coding and everybody is excited for the annual science show that Mrs Chen organises. That is until someone hacks the school website which then threatens to end to the science show because Mr Hastings is so mad. Cookie is determined to find the hacker so that the science show can go ahead. As the mysteries keep developing Cookie finds another one when she plays her computer. There is a mystery gamer who keeps beating her high scores, and suddenly Cookie's life is full of mystery and madness!

I genuinely loved reading this book, it is funny, realistic and definitely written from a child-like perspective. The comic-style illustrations are hilarious and really add to the whole text as you are reading. I would really recommend this book as an alternative read to graphic novels for Lower Key Stage 2 and upwards. The style of the writing is easy and accessible making it enjoyable to read.
