Mr. Grace's Promise

Some teachers change your grades. One changes the fate of the world.

Maddie has always loved science, and no one makes it come alive quite like her middle school teacher, Mr. Ryland Grace. His classroom is full of impossible questions, terrible jokes, and lessons that make the universe feel just a little smaller.

Then one day, he disappears.

As a mysterious phenomenon known as the Petrova Line throws the world into uncertainty, Maddie begins to realise that the man she thought was just an ordinary science teacher may have been anything but. While humanity fights to survive a dying Sun, one student must learn that the greatest lessons aren't always found in textbooks - they're found in the people who inspire us to ask why.

A heartfelt companion story to Project Hail Mary, told through the eyes of the student left behind.
