To preface this, I am not someone who often reads sciencey things, I wouldn't say I'm a clever person, I picked this up because I work with teenagers and I want to understand how things might be better for them. Also, that I watched Sarah-Jayne's TED Talk and wanted more.

The book is fascinating, even more so because Sarah-Jayne is very clear in explaining that science creates findings, not facts, so when she refers to a study we can only imagine what the real effects of, say, alcohol on the developing brain, are.

She explains in great detail how each area of the brain may develop, who has studied this and how they went about it. She talks about how different things impact that - how do teenagers deal with risk? Trauma? Education? Still, my favourite thing she explains is the same experiment from her talk, where teenagers are to move items while keeping in mind what another person can and cannot see. This alone has changed the way I interact with young people.

My only criticism of the book is that it seems to be quite a bumpy ride in terms of pitch. There were a couple of chapters that were quite above my head and I read in small chunks so I could get my brain around it, but then there were other chapters when she was explaining about blind trials and the use of controls.
