It is great that you are keen to tackle the theory so quickly, but as others have mentioned there are other excellent flying books that will help to keep your interest healthy.
For example (and doubtless others will contribute):
Fate is the Hunter (Ernst Gann)
The Shephard (Fredrick Forsyth)
The Right Stuff (Tom Wolfe)
Chickenhawk (Robert Mason)
There is a fantastic mix of fiction and non-fiction available that will teach you about some of the great pilots, hair-curling stories and you may even pick up a little airmanship along the way.
Best bit of all, I am sure all your relatives will be only too happy to buy you some books for Xmas / B'day etc
