This story is a good one . However delving into t the sexual episodes occurring between the characters is and was not necessary to make a good story . Once Taylor and Zeke got back together it was sex sex sex on practically every other page this is not necessary for a good novel too graphic. No I do not recommend this is a good read for my friends . Sorry

Ex Output:
negative

I have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.

Ex Output:
positive

Looks good but I've had mine only a few weeks and it has already begun to tear at the end tips around the perimeter of the umbrella. Not happy at all right now.
