I warned her, and I'll warn you, that I don't really know anything about poetry. I can more or less check if something scans, and I can tell you whether or not I like something, but that's about it. Nor do I really know what a proper poetry review consists of.
Disclaimers over. I really liked this book. The first poem, "Choice," literally took my breath away. There were other poems like that, to which I had an immediate emotional reaction. (These were mostly the ones about kids. Or death. Not sure what that says about me.) Others I had to read a couple times to understand. And there are also some that, to be honest, I feel like I just didn't "get". This is a problem that I always have with poetry (and certain kinds of prose too). I have trouble getting past literal meanings. But I found Brief Light to be--I don't want it to sound like I think it's shallow, because that is NOT what I'm trying to say at all. But it did seem more accessible to me than a lot of the modern poetry I've read. Very few of the poems left me with that "What the heck was that about?" feeling.
So I recommend this book, even if you aren't much of a poetry person (I tend to like the kind of poetry whose meter is so strong you can bounce up and down to its rhythm, with a very predictable rhyme scheme, and this is not that kind of poetry). It is very cheap (less than $7.00) and has some very moving poems. It's definitely a book I want to keep and come back to.
