Q: I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)

A: positive

Q: Been buying this a while now but the last 2 orders the quality has been terrible. It has greenish patches and my cat won't touch it. Waste of money as this product is expensive to just toss out. A couple of the pouches looked normal, but my cat wouldn't touch it-and he loves this food.

A:
negative
