What are the modern children’s classics?

So, I’m well aware of famous classic children’s books such as what is listed below (and of course it’s not to be meant as an inexhaustible list but just a few examples of what I mean), but I have no idea about what would be considered modern day classics that have been published within the last 10 or 15 years (for ages 8-12) and I’m curious what other people think will end up in that category eventually.

Older classics:

Charlotte’s Web

Heidi

Mrs. Frisby and the Rats of Nimh

The Phantom Tollbooth

Some newer(ish) ones I would consider classics but not necessarily published within that time frame:

Bridge to Terabithia

The Giver

Holes

The Miraculous Journey of Edward Tulane
