1) In Skyrim, there are quite a few quests that involve collecting books and you can pick up books everywhere. These books can be opened and read, and have stories and lore about Skyrim. Each one would be about three or four pages of an actual book, but there are hundreds of them in the game. Just to recap, the game presents finding and reading books as a fun activity.

In Mass Effect 3, you explore a vast and rich universe as Commander Shepard of the Normandy. Again, as you explore, the lore and background story are revealed as updates to the 'codex'. A careful reading of the codex brings you more deeply into the game

Many other games have a background story revealed through in-game books, journals or a codex.
2) Game Fiction
After enjoying a game, many gamers aren't ready to give up on the experience and can't wait two years for the sequel to come out. A game like Mass Effect spawns books written about characters in the Mass Effect universe. Most of these books are very suitable for teens.
And then there's fan fiction... fiction written about Mass Effect or other games, by fans. Some of it is amateur and some of it can be pretty good.
So there you go, that's how gaming can help to encourage a reading habit. I'm a gamer and I usually read about two books a month.
And remember, as well as encouraging teens to read, games can also encourage them to write - they may want to try their hand at fan fiction. And games can stimulate teens to try their hand at art - just look at all the game-based fan art on DeviantArt.com for example.
So I hope you can agree with me that encouraging reading is just one of the ways that gaming can be healthy for young (or old) minds.
