With a title like "Beware of God," you're probably expecting either something really heavy or something wickedly funny. I'll not mince words here, "Beware of God" is far from funny. It's heavy, but not in the philosophical jargon sort of way (though it will probably make most readers think). It's heavy in the sad, depressing sort of way. It's hard to avoid spoilers with this one, so I suggest you stop and go read it now if you plan to. Come back when you're done.
"Beware of God," reminded me somewhat of Carol Shields' Unless, though it's been a while since I read that one, so I can't say with any certainty that they really have much in common. It's about a mother, looking for answers where perhaps there are none. Looking maybe to lay blame. Needing to. You can really feel the inner turmoil the narrator is going through. Hahnel is slow with the details, and it's a bit of a mystery what it's all about, so when I started to figure it out, I was more invested in the character and felt her pain and confusion. Beautifully written, tragic story.
