Nicola Morgan is an international speaker and award-winning author for and about teenagers. She has written nearly 100 books, including novels such as Fleshmarket (currently being adapted for the London stage) and Mondays are Red, but in the last twelve years she has become increasingly well known for her passionate factual work on adolescence, with Blame My Brain - The Amazing Teenage Brain Revealed and The Teenage Guide to Stress being seminal titles for teenagers and the adults who work with and care about them.

A former teacher and dyslexia specialist, Nicola now writes and speaks around the world on a range of subjects relating to adolescence and wellbeing, as well as the reading brain, reading for pleasure and the effects of life online. Her positive, respectful and empathetic attitude towards young people naturally led her to write Positively Teenage.
