Great book, fast read, beautiful artwork

My middle school daughter and I both loved this book. There are some very heavy moments with reference to parental substance abuse, but also many beautiful, sweet moments. Love the artwork.

Beautiful story and so worth reading for anyone
It is so wonderful to see a gay love story be handled as wholesomely and tenderly as this novel. This book is pure joy. This would have been a game-changer for me 10 years ago, I am elated that teens and adults today can grow up with something like this. A lot of queer novels tend to talk about dark topics: HIV, homophobic parents, drugs, ostracization etc. It's probably because the people writing and producing the content were young during an era when it was tougher to be queer than now. Heartstopper does not shy away from the tough issues but always the main theme is a loving relationship! A tender and beautiful romance between two boys. I would have loved this during my high school days. Get the books! they are a quick read filled with beautiful comic like drawings and then see the show on Netflix!

Loved it!
Format: Kindle
I really enjoyed reading this. I saw the Netflix series first, and that brought me to looking up the books. This gives so many feel-good vibes, and it is so sweet. I enjoyed the extra info not mentioned in the tv show and seeing it from different characters’ perspectives.
