I'm looking to buy a book for someone with a penchant for fictional/religious/artefact/mystery type books. It's a secret santa so I've no idea of what's been read already, neither can I enquire. I shall assume the popular "Labyrinth" has been read so looking for something along that ilk, possibly not as well known? I'd be grateful for any suggestions. It's not a genre I'm over familiar with so I don't have any authors to research.
Thanks :)
