It's an okay book. A lot of people absolutely love them, so you might like it. Why not just give them a try? They're not even that long. The type is just humongous.
To me, the first book was interesting at the beginning. Then, it just got kind of stupid. At the most 'exciting' or cliff-hanging moments, I find that the book turns rather boring. It also moves really quickly and reminds me of a book that a fifth grader would right. One second they are playing baseball, the next they are being attacked are are running around the country. It didn't need to be written so quickly. And, it just seems kind of stupid to have every single guy the main character meets obsess over her.
