Master of Deceit is a balanced and informative look at Hoover and the FBI during his administration. It is not, by nature or design, an exciting story...but is definitely informative and would be useful to someone doing research or looking at the history of the FBI. I would definitely recommend it to anyone looking for a book to begin research with as it is well researched and has lots of source notes.
Wasdin doesn't talk down to teens, indeed I'm not sure he specifically was writing to teens; but it was a required reading book for me, and I enjoyed it more than I thought I would. Yes, there were those very typical macho things contained within it; a little bit of testosterone and a bit of swagger...but then, getting into the SEALs is a big deal and a challenge and SEAL Team Six even more selective...so he probably can be forgiven....I especially like that he equated some of his mental strength to his years of physical abuse; the ability to distance the mind from unpleasant and hurtful circumstances is real and made his story a lot more personal and human. He even shares his regrets for how he is less demonstrative and more distant than he'd like to be given his job and his background. I really enjoyed this, and think it would be very appealing to anyone wanting information on how the military works, or who just enjoys realistic contemporary reading.
By contrast, I also read The Warrior's Heart...which WAS a rewrite specifically done for teens from a title done for adults. Evidently he did a good job, since it was a bestseller for him as an adult title....but as a teen book, it kind of falls flat. The author decided to try his story in a sort of "choose your own adventure style"....using a lot of "what would you do" portions....but overall it comes off like he's talking to a little kid....and a bit patronizing.....I don't know if that was an editing decision, or if the person working with him to redo his story for a younger audience didn't know the age range they were trying for (everyone under 18 is a little kid mentality maybe?)...but I didn't enjoy it at all.....it definitely seemed more "I am awesome" with lots of swagger and less substance.
