Looking for a YA book published 2008-2015-ish. It is a kind of steampunk-y story about some children whose father has disappeared. He’s a Victorian-ish explorer and there are still vast expanses to be explored. The kids follow some clues and find a hidden world…maybe in a cave? I think the father was part of some sort of explorer’s society, too.
Stump the Bookseller
New format, same book stumper solving.
Is it one of the “Mapmakers” trilogy books by SE Grove?
No, but that looks good too!
Maybe Larklight, by Philip Reeve?
Do you have any idea how old it is? That would help narrow it down. Thanks
