I logged in especially to second what lukewrites has said.

My kids both started on and enjoyed graphic novels, then progressed to reading chapter books without pictures etc, I'd say in part because of the graphic novels.

My first daughter I managed to flip the switch for reading through Tintin and other graphic novels. My younger daughter skipped that entirely. She started reading later than the first, but jumped right in to longer full length books that were captivating for her (they were series she had seen her sister read).

I completely agree that we can encourage but reading needs to come naturally to them. You can't force-feed curiosity and passion, which is what reading is all about for young people.
