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.

I have adored Dean Konntz since I was in High school, I remember reading Phantoms for the first time and not sleeping through a night for a week! He is simply the best author I've ever found, he grabs you in the first page and doesn't let go until he's done what he wants to.I too was very Wary of the title, but I've found I'm not thinking about Frankenstein when I'm reading this, I'm just too engrossed in the characters! I can not wait until book two and I am so glad he wrote this instead of following through with making it a movie as he mentions in the begining of the book.

Positive
