"Eden, Eli, Marwan, and Ilanka barely know each other beyond having a class or two together. But when they are all summoned via messaging app to an empty classroom after school, they find a small cube sitting on a desk. Its sides light up with rules for them:

Do not tell anyone about the device. Never leave the device unattended.
And then, Take me with you . . . or else."

I was really interested in the premise of this book! And it seemed like the lighter-quick read I was looking for, but unfortunately it fell pretty flat for me. The world and characters weren't very built or well rounded so I wasn't invested in anyone, definitely takes away a lot from a story for me personally. But the plot was good and paced well enough to complete it! Overall, I have it 3/5 stars.
