The Wreccas live in the darkness, filth and squalor of Underneath, and love mess and mischief.

The Guardians live Topside in Greenwich Park, unseen by humans and quietly looking after the most precious thing in the world: Time. Sofi Mossel was born into the grubby world of the Wreccas - but has been adopted into the magical world of The Guardians by Old Father Tim and his grandson Tid.

Sofi wants to forget the past and be a real Guardian. But then a massive earthquake strikes. Human and Guardian time are ripped apart - and no one, not even the Guardians, knows what to do.

The answer lies with Sofi. But before she can save everyone's future, she has to seek help from the pat...

Delicious sequel to The Time Wreccas.
