A story- ill update the title later

It's 1969... August and Astrid were one minute, hugging their father then the next.. a bomb explodes. Five years later, August and Astrid believe they are the last ones alive.. until they get kidnapped and learn that they weren't the only ones. Will they escape and find out the truth or will they never see the lights of day again?

Me and my friend are making this so- it's gonna be weird-
