An awesome person on Discord shared the link to this story a couple weeks ago (please tell me your Tumblr username again so I can credit).
This is the story that The Secret Gardner is a loose sequel for. I’ve wanted to read it for a long time and was pleased to discover that it was actually published in many languages, including English and Arabic! If you can find it in your country, support the artists and publishers by buying it.
