Ten billion worlds.
One impossible murder.
Two orphaned teenagers.
Isra and Arwen believe they lost everything the night their parents were murdered.
They're wrong.
Someone has been watching them since the day they were born.
Someone knows the truth behind their parents' deaths.
And someone will destroy ten billion worlds to keep that truth buried.
Now two ordinary teenagers must cross impossible realities, outrun creatures that should never exist, and solve a mystery older than time itself.
Because if they fail...
every world loses its story.
