Frozen in Time by Ali Sparkes

Some boring summer!! Just when Ben and Rachel think the summer would be boring, they find a secret in the backyard. What they find sends all into an international mystery years in the making. How does a British government clean-up car, the Cold War,  Chernobyl, and a missing uncle help solve a 50 year old mystery? Can they really trust that helpful librarian? (Can you ever trust a helpful librarian??) The biggest question could be how do teens from the 1950s learn to be like teens today when everything you do was not allowed during that time? Will help arrive in time or will Ben and Rachel's new friends not make it to get to the bottom of what really happened to their father? For those of you who love a great mystery wrapped in one of the wildest sci-fi inventions, you will not want to put this down.
