This story didn't wow me. It did seem to be out of a book of formulas for urban fantasy. I'm still not really sure what "the time of the boat lift" is, nor what the significance of the boat lift actually is. Well, at least not that I remember a couple weeks after listening, but that makes the title pretty ineffective for me.
I was really excited to see a story that combines logic and magic, because there's really no reason the two are incompatible. But I was annoyed that a textbook logical paradox was the way to win the day--it felt like the climax to a Golden Age SF story when that was still a new idea. That idea is about as novel these days as "And those two people were Adam and Eve". It's not that it's a bad idea, it's just that it's an idea that has been used to death.
