The Giant Jam Sandwich

Where the Wild Things Are.

Off the top of my head:
"Something From Nothing" by Phoebe Gilman
"Love You Forever" by Robert Munsch
And "Where the Sidewalk Ends" by Shel Silverstein

Corduroy

my is jack and the bean stock

The spider and the fly

The story of a seagull and the act who taught her to fly. Very meaningful, pure beauty.
Totto-Chan: The little girl at the window. its a japanese book but im sure you can find english version easily as its pretty popular. Heart warming and lovely.
The secret garden. My all time fav.
Little Prince. Just poetic.

Animorphs or the cat Warriors
Shit, maybe the Lightening Thief
I read a lot so it's hard to pick a fav
