I LOOOVED trixie Belden a a pre-teen and young teen. My daughter wouldn't even entertain the idea of me reading them to her.
My son who is generally the better reader absolutely rejected the Chronicles of Narnia (too boring!) and it has crushed my heart.
My daughter loved The Hobbit (son was just ok with it) and that almost made up for everything else.
When they were young I tried to read The Wind in the Willows to them and they both found it very boring. When they were in elementary and we were driving to various kid events we went through a lot of audio books and they really enjoyed it read aloud. They also liked The Jungle Book on audio (though I felt the reader wasn't very good) and I know they wouldn't have tolerated reading it to them. I kinda wish I had pushed audio books earlier or tried more audiobooks - maybe I'd have a Narnia loving family.
