Ada Twist, Scientist by Andrea Beaty

Ada Twist has always been hopelessly curious.

Why are there pointy things stuck to a rose? Why are there hairs growing inside your nose?

In this book, Ada embarks on fact-finding missions and conducts scientific experiments, all in the name of discovery!

When her house fills with a horrific, toe-curling smell, Ada knows it's up to her to find the source. But, this time, her experiments lead to trouble.
