This is a wonderfully entertaining, well-written and thought provoking story. The author did a superb job of developing character and plot, leaving the reader with a lust for the story to continue.

I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.

Ex Output:
Negative

Okay, first off, I love Loving Family. I have the Twin Time and all of the accessories AND the old dolls. But when I received the new dolls as I gift, I was shocked. Mattel has completely changed the dolls from sleek to chunky. These dolls apparently look a lot like the ones they made back in the 90's. If you want dolls for your Loving Family house, try to get the old ones on eBay.
