Cover blurb
Young children can be difficult. Tantrums, toy-throwing, not wanting to go to bed, whisking their mothers on dangerous journeys throughout all of time and space...

Jason wants Benny’s son Peter to have a normal childhood. Peter has other plans. And unfortunately, Peter also has Benny and Jason’s Time Rings. And knows how to use them. Even more unfortunately, the fact-obsessed, tentacle-faced Grel have built a time machine, and they’re after Peter.

So Benny finds herself on the run, landing in frightening festivals and deadly deserts, facing ridiculously inaccurate robot doubles and hideously accented tourists, in what can only be described as a sort of chase...
