Underground.
One thing is certain: Ollie\'s quest to right past wrongs is about to open up a whole new can of wormwalkers in the extraordinary underground world he now calls home..
It\'s also the only idea he\'s got.
Leaping into that water, he knows, is a monstrously bad idea.
The less-good news? It\'s hidden at the bottom of a deep, dangerous lake.
The good news? There might be a solution.
And he thought he had, until he sees the stark truth spelled out in black-and-white: His friends are in danger, and it\'s all his fault.
Ollie had only wanted to make things better at Herrick\'s End.
Out of time.
Underwater.
