About this book

One day Sophia begins to feel a little bit unwell. At first, she's just tired and a little achy, but before long her symptoms have moved on to vomiting, fever, and diarrhoea. What's causing this illness, and who can help her recover? 

Luckily, the Diagnosis Detectives are on the case. With the help of Philly the neutrophil, Tia the T-cell, Buddy the B-cell, and Mo the Monocyte, any nasty viruses, bacteria, or fungi will soon be captured and destroyed.

Follow the immune system detectives on a tour of the body as they identify a list of symptoms and suspects to try and cure Sophia. 

Along the way, they explain the science behind various illnesses and bodily functions and demonstrate ways of helping to protect yourself and others from illnesses.

The science content in this book is aspirational, explaining different antigens and immune system reactions in detail and with the correct terminology. This information is complemented superbly by fun characters and brilliant, immersive illustrations which bring the inside of the body to life and add context and anatomical clarity.

Featuring DIY science experiments, tons of clear information, and excellent anatomical illustrations, this would be a perfect book to use alongside Key Stage 2 science topics on the human body, or for more general health and hygiene topics in PSHE sequences.
