Well, 'cause we're pretty? Nah, that's probably not the answer you were looking for. In all honesty, we can see two possible answers, the first sounding totally conceited and just plain wrong, and the second being the truth.
1 - (Totally conceited answer) Because we're extremely intelligent women who just happen to be right. About everything.
2 - (The truth) That's actually not a question we can give an answer to. You'll just have to read our thoughts on the books and see if they jive with yours. The good thing here is, if we liked a book and you totally hated it, you can read our reviews and read the opposite into them. On that same note, if we happen to like a book and you do too, it would seem our tastes are similar, therefore, you'll be able to look for some new books. That's why we post reviews on books whether we like them or not. Remember, we're going to be honest about a review, so not all of them will be favorable. We will, however never be cruel. We'll give you our thoughts, good and bad, and you'll be able to see if you like the way we think or not. We just really hope you'll like the way we think ;)
