Query: Great series

Keeping in mind that this is of a light, fun genre, it's a very good read. I have trouble writing "excellent" only because I measure against the books that make me want to call in sick so I can keep reading, like the Girl With a Dragon Tattoo series, or even the Hunger Games. This series is really fun, though, and the writing is good (though if I read "you're my world" one more time I may puke). Aside from the romantic element (which is still mostly good), the comedy is good and the plot for each of the series is never boring and has lots of surprises. Plus, the lead character and the author are both animal people, which makes them good people. The proceeds from these books are donated to animal organizations, and they aren't expensive, so if you're on the fence about them, perhaps that could help tip the scale for you. You won't regret it, though - they are a lot of fun.
