We all know that growing up is hard to do, and sometimes the only thing that makes it better are the reassuring words of someone who has walked that bumpy road just a few steps ahead of you and somehow ended up as a fully-functioning adult. Carrie Hope Fletcher is that person.* Thanks to her phenomenally popular YouTube videos, Carrie has become an 'honorary big sister' to hundreds of thousands of young people who turn to her for advice, friendship and, most of all, the knowledge that things will get better.

Carrie has created a safe and positive space for young people to connect and share their hopes and concerns online, and now she will share her most personal thoughts and experiences in her first book, ALL I KNOW NOW. Part memoir, part advice guide, it will include Carrie's thoughts on some of the topics she's asked about most regularly: bullying, body image, relationships and perhaps the scariest question of all: what does the future hold for me? With warmth, wit and a sprinkling of hard-won wisdom, Carrie will provide the essential tools for growing up gracefully . . . most of the time.

*Although she did recently post a video about how to pee in a onesie. So the definition of 'adult' is a bit flexible here . . .
