Under a Blitz Sky

A family mystery remains unsolved and it's up to 13-year-old Danny to uncover the truth. So, after moving to Wales to live in his great-great grandfather's cottage, weird things begin to happen, disembodied voices, the ticking and the tocking of clocks that aren't there. And someone is speaking German, and about Hitler. All this propels him into the past so that he can save the future and his family's reputation.
