Tomorrow Code

It had happened before.
Burnt Mountain, Alaska.
Novosibirsk, Siberia.
Now it is about to happen to a thriving city.
A city with a population of 1.3 million people,
all of whom will be wiped out in a blink.
Unless it can be stopped.
Teenagers Tane Williams and Rebecca Richards hold the key to stop the destruction.
A message from the future.
Instructions that cannot be ignored.
Tane and Rebecca must act - and fast.
The survival of the human race depends on it.
