Tripwire starts slow, picks up a ton of steam, and then ends too quickly. Boag is a pretty cool character, which is good since he is in virtually every scene, and you really start pulling for him more towards the ending. Other characters are fairly well-drawn, like great sketches rather than finished masterpieces. That is fine with me. Makes for a shorter book, though, and it's not all that fast-paced despite its brevity. Worth your time if you like revenge dramas, but not all that deep. Still, Garfield is a fine writer even though his ending seems more like it was rushed to meet a deadline. I am eager to try Death Wish and would read more of his books based on how I liked this one, which is more 3.5 than 3.0.
