What books should I buy?

I recently got a Barnes and Noble and a Best Buy gift card. They both sell books which I want to buy but I've no idea which ones to pick, there are just so many!
Do you guys have any suggestions?

To give you an idea of what kinds of books I'm looking for here's a list:

Margaux with an X by Ron Koertge (R.ed here)
The House of the Scorpion by Nancy Farmer (R.ed here)
The Perks of Being a Wallflower by Stephen Chbosky (R.ed here)
Marcelo in the Real World by Francisco X. Stork (R.ed here)
Battle Royale by Koushun Takami
Cider House Rules, The by John Irving
Fight Club by Chuck Palahniuk
Elsewhere by Gabrielle Zevin
Girl She Used To Be, The by David Cristofano <--oh my gosh darn, this one is sooo great!
Heartsinger by Karlijn Stoffels
Howl's Moving Castle by Diana Wynne Jones
Q&A by Vikas Swarup
Stargirl by Jerry Spinelli
Tell Me That You Love Me, Junie Moon by Marjorie Kellogg


I included the reviews for some in case anyone that comes across this post hasn't read those books. They are REALLY good. :D

So can you guys help me here? Your suggestions don't have to be about books similar to those I listed, you can just tell me about some recent reads you loved. If you reviewed them you can leave a link. I love looking at reviews of books before purchasing them. :)

THANKS SO MUCH!!! :D

If ya'll help me I'll love you forever okay? I know that may not mean anything coming from a stranger but at least now you'll be able to tell someone "I have someone that loves me forever do you? I don't think so. Ha!!!" hehe :)
