Mean Free Path

“Lerner [is] among the most promising young poets now writing.”—Publishers Weekly

“Sharp, ambitious, and impressive.” —Boston Review

National Book Award finalist Ben Lerner turns to science once again for his guiding metaphor. “Mean free path” is the average distance a particle travels before colliding with another particle. The poems in Lerner’s third collection are full of layered collisions—repetitions, fragmentations, stutters, re-combinations—that track how language threatens to break up or change course under the emotional pressures of the utterance. And then there’s the larger collision of love, and while Lerner questions whether love poems are even possible, he composes a gorgeous, symphonic, and complicated one.

You startled me. I thought you were sleeping
In the traditional sense. I like looking
At anything under glass, especially
Glass. You called me. Like overheard
Dreams. I’m writing this one as a woman
Comfortable with failure. I promise I will never
But the predicate withered. If you are
Uncomfortable seeing this as portraiture
Close your eyes. No, you startled
