"Echolocation refreshes one's sense of the thrilling necessity of poetry. Dedicated to 'all those who navigate by sound in the dark,' it is meant for an 'us' that includes the whale, the bat, the frog, the river, as well as our multifarious, ardently curious, startlingly ingenious human Selves. Reilly's tour-de-force opening suite of poems is conducted, with her uniquely grave humor, like a lepidopterist's outing in the spotting, not netting, paradoxical fragilities of metamorphic selves and echoes of selves attempting to locate one another."--Joan Retallack Poetry.
