I actually just got the trilogy in the mail today ($30 from amazon, originally $54). I received them around 4:00 PM and I finished reading the first book by 10:00 PM. Assuming the same happens with the second and third books, I'm really gonna wish I had borrowed them instead of purchased.
The first book was definitely entertaining...I literally couldn't put it down until I finished. That said, it didn't leave an impression on me after reading it like I was expecting after hearing all of the rave reviews it's received. Like previous posters have said, it's obviously geared toward teens and, even though the subject matter is more mature than the twilight series, the style of writing isn't all that different. No lengthy descriptions of scenery, no really detailed back-stories of key characters, etc.
Bottom line: I'd recommend reading at least the first book (haven't read the others yet), but borrow instead of purchase if you can (unless money isn't an issue).
Collins is not a good writer. She can pace stuff well, and write some entertaining set pieces, but her actual writing is extremely amateurish. It's particularily evident in book 3. Books 1 and 2 had an entertaining storyline to make up for the weak writing, but book three is as generic as they come, and Collin's lack of narrative skill is especially evident here.
I agree...While I was reading it, I thought that this is what a book would be like if I attempted to write one, lol. I sometimes come up with what I think are cool ideas for a book, but I just don't have the skill or the patience to do more than get to the point, write down the facts, and move on, instead of really developing the characters, the scenery, and the storyline.
