If unluckiness runs in families then Benjamin must be Andrew Mayhem's even unluckier cousin. You can't help but feel for this guy. Just as you think it can't get worse for him, another barrel of awful empties on his head. Just like Strand's other comedic character, there is nothing that will shake his faith that all will be right in the end and through it all he retains his optimism. We have to admire him even as we cringe (not figuratively, I actually did physically cringe several times in this book) when he suffers one painful indignity after another.
I nominate the parasite for nastiest whatever I have ever encountered in a horror novel. Not sure what exactly the bugger is, but he is 100% unpleasantness.
If you like Andrew Mayhem, you will love this book. If you haven't read any of the Mayhem series, get it anyway. Fun, horrifying, and filled with witty one-liners. High theater of the absurd. 4.5 stars.
