The Sentry, like other Joe Pike books, contains a lot of action and heroic measures as Joe continues to help the less fortunate and downtrodden simply because he was in the wrong place at the right time. What's different here, though, is that the people he helps aren't really good guys and he falls for a woman who knows how to play him. She pushes all his buttons and he fell hard. And even when he learns the truth, he can't back away from doing what he considers the right thing. This story shows us that Joe has a human side - he is vulnerable and lonely, looking at his life and wondering where a special someone could fit in. In a parallel story, we see that Elvis had that life but it fell apart because of his lifestyle, and Joe has got to be wondering if it's even possible.to leave this behind. Chances are it's not, because Joe has never been one to just walk away from injustice but like the arrows on his shoulders, he's looking forward to the next chapter. It's a great story - I'm listening to it again, and I'd recommend it to anyone who loves action, a bit of romance, good triumphing over evil, and friendship that endures no matter what.
