Johnny Maxwell and his friends have to do something when they find
Mrs Tachyon, the local bag lady, semi-conscious in an alley . . .
as long as it's not the kiss of life. But there's more to Mrs
Tachyon than a squeaky trolley and a bunch of dubious black bags.
Somehow she holds the key to different times, different eras –
including the Blackbury Blitz in 1941. Suddenly now isn't the safe
place Johnny once thought it was as he finds himself caught up more
and more with then . .
