Meet the microbes!

These tiny organisms - that can only be seen under a microscope - are absolutely EVERYWHERE. In fact, they're even living inside our bodies, travelling through outer space and swimming in the world's seas.

And while some microbes can make us sick, many of them actually keep us well, and even help to keep our planet happy and healthy.

Step into the incredible world of microbes in this fascinating picture book by Dr Emily Grossman about the miniature life that surrounds us.
