As of now, there are a specific number of Heartstopper novels. However, it's hard to give an exact count without looking up the most recent updates. You can search online or check at your local bookstore for the most accurate number.
I think Amazon Kindle also has a wide range of comics. You could search there. Also, some official comic publishers' websites might have Heartstopper available for reading.
The ending of the Heartstopper comic is sweet and heartwarming. Nick and Charlie's relationship blossoms and they face challenges together, emerging stronger and more in love.
The number of Heartstopper graphic novels keeps growing. Currently, there are a handful, but you'd need to check the latest updates from the publisher or relevant sources for the most accurate count.
The number of Heartstopper graphic novels is not fixed. Currently, there are approximately four. However, the author might come up with more in the future.
