The marked children - Thea Booysen

Goodreads 4.31

A mark. That’s how it begins. The first sign you’ve been chosen.

Sixteen-year-old John’s life changes when he discovers a sinister black symbol on his arm. Little does he know that thousands of children across the world woke up with similar marks, but went missing shortly thereafter.

It’s like they disappeared from the face of the Earth. Where did they go?

Unfortunately, John is about to find out.
