About the Book

Substance: Fuzzy Mud

Chemical compound: Unknown

Danger level: Deadly

Bright, polite and hard-working Tamaya is on a scholarship to the prestigious Woodridge Academy. Every day she and seventh-grader Marshall walk to school together. They never go through the woods. Ever.

School poses its own set of problems for Marshall. Once a popular, out-going young man, Marshall is now a frightened, miserable wreck. All because of Chad. Chad is a bully, who makes Marshall’s life utterly unbearable. One day, hoping to avoid Chad’s taunts, Marshall and Tamaya decide to go through the woods … And what is waiting there for them is both startling and sinister.

The next day, Chad doesn’t turn up at school – no one knows where he is. Tamaya’s arm is covered in horrible, burning, tingling blisters. Feeling responsible for his disappearance, the two unlikely heroes set out into the woods to rescue Chad. However, the town is about to be turned upside down by the mysterious, frightening Fuzzy Mud …

This is a funny, exciting biotech thriller full of adventure, mathematical puzzles and terrifying mystery. The book also tackles a range of serious issues such as bullying, belonging, environmental danger and the impact of uncontrolled scientific exploration on our society. This is a creative, thought-provoking read, with daring, intelligent characters, that zips along at a ferocious and fearless pace.

Encourage the children to use a range of books to research micro-organisms and to record anything they already know about bacteria and viruses.

Allow some time for the children to explore the double page spread before Chapter One – let them familiarise themselves with the setting and places in the story.

Is there anything that puzzles them about the book?

Do they have any questions?

Use the children’s questions to initiate a discussion – they will be more engaged if it is something they are genuinely interested in. Some questions might be answered easily, whilst others may need to be explored at a later date or after further exploration of the book.

The perils of science Bravery vs cowardice
Looking after the environment Friendship Danger


Write a diary, as if you were Marshall, describing your day to day life since Char arrived at school.

Vocabulary journal

Identify a set of target words for teaching. Suggestions are given below, but chose those most appropriate for your class or group.
