When Isaac fails physics, his parents hire a teacher to give him private classes. Isaac hates the idea, but he is very surprised when he meets her - it’s Niko, a girl almost his age. And he will be even more surprised when, trying to give her back the pencil case she had forgotten at his house, he sees her enter a very strange tower - a tower that doesn’t seem to obey the

When he sneaks inside, Isaac sees all kinds of strange things: levitating objects, inexplicable colour changes... But it’s not magic - it’s physics! Soon he will discover that everyone in the tower has a gift for physics and they dedicate themselves to going on missions, solving physics problems that could affect our world.

But there is one problem that they might not be able to solve. Because the shadow of the First Ones is upon them, and their leader won’t stop until he gets what he is looking for...
