A while ago, probably when she realized that I'd given up sleeping to read some semi-addicting fanfiction (yes, I used to read that), my sister (a.k.a. The Other One) informed me that if someone wrote a series, I could be addicted to it.
Much as it generally pains me to admit it, The Other One wasn't wrong. I tend to read books that come in series, and I tend to read the whole series. I've read all of -- The Twilight Saga; Harry Potter; Midnighters; The Pit Dragon Trilogy; The Uglies Trilogy; the Hollow Kingdom Trilogy. I've also read the first three Percy Jackson and the Olympians books, with the fourth and fifth in my To Read stack, and 4/5 of the Wicked Series, which I thought was a tetrology (weird story that).
I think we can establish that that's my 'type,' as it were. Hello, I'm Me, and I am a Series addict. Maybe it's because I don't like to see the characters I loved go. Maybe it's because I can't bear the fact there's a part of the story that I'm missing (I do so hate not to be in the know on things). Either way, I think I've found a real trend here.
How about you? What's your 'type' in the book world? Do you have a 'type' irrespective of genre?
