"The Hidden Room" is filled with treasure gathered from over five decades of some of the best poetry ever written in Canada. Almost all of the poetry P. K. Page has published in volume form is here, all the way from "Unit of Five" (1944) to "Hologram" (1994), together with a good many unpublished poems and poems hitherto published only in magazines, from all stages of her career. A section of luminous new poems completes the volume. "Evening Dance of the Grey Flies" and "Hologram" appear substantially as first published, though virtually every other section has undergone thoughtful reassessment by the author with the assistance of editor Stan Dragland. "The Hidden Room" is something more than simply a mechanical Collected. The inclusion of uncollected and new poems has demanded a re-choreographing, a reassortment of familiar poems into new families. "The Hidden Room" is quite possibly the best collection of verse ever published in this country. This is the essential, rather than the entire P. K. Page, a lifetime of work that any poet would be proud to call their own.
