French language books

Looking for books to read in French to support my French learning. Mostly fiction but nonfiction is fine too. I'm not into mystery or romance.

I'm using an e-reader so I can easily look up words I don't understand

I just finished En Finir Avec Eddy Belleguelle and loved it. I tried Les Années by Annie Ernaux, but unfortunately the level is slightly too high for me. I started Moi Qui n'ai pas connu les hommes, but it was too dark for summer reading. I've already read le Petit Prince and Harry Potter in french.

English books I've liked recently are: North Woods, Margo's got Money Troubles, Song of Achilles

Merci tout le monde!
