If you could spend a day with any book character doing whatever you wanted (in our world or in theirs) who would you choose to spend the day with and what would you do? (No unmarked spoilers please!)

I would spend the day with Piranesi from the book of the same name by Susanna Clarke and ask him to give me a tour of the House. It's such a fascinating world and Piranesi is such a sweet character who I feel would be really fun to talk to.

My second pick would be Mosscap from A Psalm for the Wildbuilt. We'd spend the day hiking and talking about science and books and then finish up with some tea and stargazing. I don't think Mosscap and I would get very far on a hike since we both have ADHD but we would have an amazing time making the attempt.
