A book where the main character is skilled at lying

Looking for books where the main character is skilled at lying.

I don’t mean that they tell a single lie and it’s an important plot point, but instead that being a liar, con artist, or likewise is an important part of who they are as a person.

Bonus points for YA but it’s not a requirement. Thanks! ☺️

Edit: thank you all! I have so many to add to my TBR (and a couple that were already on there that get to be bumped up a lot!)—I appreciate it!
