In the citation accompanying Kay's recent award of the prestigious Ruth Lilly Prize, Christine Wiman wrote: Kay Ryan can take any subject and make it her own. Her poems-which combine extreme concision and formal expertise with broad subjects and deep feeling-could never be mistaken for anyone else's. Her work has the kind of singularity and sustained integrity that are very, very rare.... It's always a dicey business predicting the literary future...[but] for this reader, these poems feel as if there were built to last, and...they have the passion, precision and sheer weirdness to do so.

Salon compared the poems in Ryan's last collection to Fabergé eggs, tiny, ingenious devices that inevitably conceal some hidden wonder. The exquisite poems in The Niagara River provide similarly hidden gems. Bafflingly effective, they seem too brief and blithe to pack so much wallop. Intense and relaxed at once, both buoyant and rueful, their singular music appeals to many people. Her poems, products of an immaculately off-kilter mind, have been featured everywhere from the Sunday funnies to New York subways to plaques at the zoo to the pages of The New Yorker.
