I hope this isn't unwelcome, but I have book recs for your Goodreads challenge! The Misadventures of Benjamin Bartholomew Piff, School of Fear, Sister's Grimm (it's a whole series, I love them), Gallagher Girls, Wait 'Til Helen Comes, Wide-Awake Princess, Brand New Emily, Replay, and Etiquette & Espionage are the ones that come to mind right now. I don't know how many of these you've read, and a lot of these are easy, light hearted reads, but they're short and I really enjoyed them.
GALLAGHER GIRLS IS MY FAVOURITE OMG YES.
Also lol don’t worry, definitely not unwelcome! I always love getting book recs and I literally asked you :)
I have read the first book in the Etiquette & Espionage series. I might actually continue with that one since I can borrow them from a friend (I’m a little broke right now lol).
I don’t think I’ve heard of the rest but I am painfully intrigued by Sister’s Grimm and School of Fear! I’ll definitely look them up.
(Hope you don’t mind me posting this. I’m at work and so I can’t add them to my TBR right now :))
