So I started to read popular penguins and I'm really loving them.
I've read:
Picture of Dorian Gray
The Happy Prince and other stories
Gulliver's Travels
Casino Royale

and at the moment I am reading The Chrysalids and I'm loving all of them

What are some other good recommendations?

The Little Prince by Antoine de Saint Exupéry is good, and I found The Perks of Being a Wallflower by Stephen Chbosky good, as well.

But anyway, to match with the genres of the books that you've just mentioned, Anne of Green Gables is nice, and The Indian in the Cupboard as well.

*fails at giving recommendations*

oh oscar wilde hnng.
i don't know if they're penguins, but
the catcher in the rye
anything by franz kafka
the great gatsby
the curious incident of the dog in the nighttime.

/fails as well
