These poems are a modified form of sonnet, each poem having 14 unrhymed lines, perhaps an octet and sestet, the final couplet sometimes constituting a switch in topic or a comment. Most of the poems come from previously published collections. (The afterword explains the inspiration of the sonnet to Cole.)
Cole definitely has technique, and uses themes that are fairly common in poetry with with notable style: nature imagery, reminiscenses about parents, sexual love, addiction, war. A Cole says, "Trees, mammals, fire, snow—they are like emotions."
I like Cole when he relaxes and riffs on an experience, as in the poems "Melon and Insects" and "My Tea Ceremony." Some other poems are also quite naturally evocative, such as "Gulls" and "Haircut." Simple language also works well as it leaves a bit of a question mark, as in the very ending of "Oil & Steel" where Cole says that his father "gave me a knack / for solitude, which has been mostly useful." His philosophy is sometimes quite intriguing ("How poignantly emptiness cries out to be filled"), sometimes a bit pat.
Sometimes, the parts don't quite add up. It's OK to assign the color pale yellow to emotional reassurance, but why should it be like onions? And take his phrase "A bee scribbled its essence between us." That's a clever way to invoke the errant motions of a bee, but Cole does not bring me any closer to the bee or to the person I'm with in the poem. The word "essence" is abstract and actually rendundant.
