Well, I have to agree. Post-Potter Depression has really set in. I really miss the warm and cozy common room, the interesting and quirky classes, and yes...even snape and Harry's relationship (especially after reading book 7...soo sad)...made me view snape in a whole new light.
As for your "potter fix," try Philip Pullman's "His Dark Materials" Trilogy begining with "The Golden Compass." They're awesome books with really lovable characters and a very interesting plot.
Also, there's "Magyk," "Flyte," and "Physik" in that order (with a fourth coming out in April). They're the Septimus Heap series by Angie Sage and they're pretty good. When I finished reading the first one I kind felt disappointed cuz it wasn't Harry Potter, but I picked up the second and then the third, and realized that I was hooked anyway. They're really good.
If you want something a little more grown-upish (I'm 24) try The Thirteenth Tale by Diane Setterfield...It starts off a little slow but then really picks up and you can't put it down. Seriously interesting and a little spine-tingly creepy (but in a good way). Kind of reminds me of the old ghost stories I would read as a kid (remember goosebumps?haha).
Then of course there's my all time favorite gothic-romance: Jane Eyre. What Twilight is for Teenagers, Jane Eyre is for everyone. It's full of big gothic settings: huge estates and mansions, and large expanses of land. Also, the male lead is very "edward cullen" (from twilight) but all grown up and sexier. Give it a good try...I promise you will love it.
Another suggestions is...if you've never read the Chronicles of Narnia, start with "The Magician's Nephew" because is sets up the story for "The Line the Witch and the Wardrobe" and makes it more interesting.
Well, that's all I've got for now....Hope it helps! Enjoy! =0)
HUGE reader & writer, so I only included books that have a good combination of characters, settings,plots and sub plots. Any "fluff" that I've read, I left out. Those are all garunteed winners.
