Time Travellers and the Lost Girl - S Collins - Bog

Chip and Skip have only just returned from their second time-travelling adventure and already they've plunged head-first into the next one. And while the magic glasses may have sent them over 100 years into the past, their destination seems strangely familiar. Still, with a little girl in danger, a wicked aunt and missing parents, the time travellers are soon fighting to save not only their new friends, but themselves as well. Will they succeed, or this time have they taken on too much?
