James wishes he could go back in time. Back to when his mum and dad were together, when he had one home, when his family laughed and climbed hills and went to the movies.

After meeting the enigmatic Yan, a girl who looks at the world differently, James discovers time travel might not be impossible after all.

But if James can live forever in one of his six favourite memories, which one will he choose?

In a place where retro Australian Woman's Weekly birthday cakes, old Commodore computers, chaotic rideshare vehicles of the future and spacemen all collide, Countdown to Yesterday is a contemporary novel touched with philosophical and science fiction ideas for young readers.
