A brave escape

"Alba lives in London in the UK with her family. Her dad is a scientist. A breed of superbugs is destroying all the apple trees in the world and Alba's dad is working hard to save them. He has the last apple seed left in the world safely at home. Max, from the lab, sneaks into Alba's home and tries to steal the seed. Alba escapes with it, but Max shrinks her to four inches tall! She has to get the seed to her dad in the lab and save the apple trees. She will need to dodge Max, who is following her. Will she succeed in crossing the city and getting the seed safely to Dad? Will she ever be a normal size again?"--Back cover.
