These poems are filled with awe and celebration, sadness, and ironic humour as Shepherd explores the themes ofhuman relationships with the natural world including connection, alienation, and the negative impacts of human activity on nature;interspecies kinship ecological as well as animistic and shamanic; andintersections of ecology and industry.

Shepherd uses numerous voices and perspectives, and such arrangements bring about a variety of moods. Whether his subjects are starlings or tamaracks, woodchucks or grizzly bears, the ever-present magic of nature guides not only the mode but directs each poem s tone toward some unique perspective:

Some spiders know the correct use of magic knots to tie a cluster of Oregon grape into one single dusty purple berry. If a

black bear swallows it under the right moon he or she will become a powerful shaman,
able to speak the languages of spiders.

But while there is a dominance of the natural world found in the poems, they also reflect the numerous meanings of the title: a shift of perspective or point of view, physically moving or shifting position, transforming or changing form or physical appearance, shifting gears while driving a vehicle, working the night shift, and so on.The book’s titleis also taken from the title of one specific poem in the collection that encapsulates some of these central ideas.

Living and working on the land andbodily experiences of specific places also have their place in Shepherd s poems. These portraits ensure a kind of visceral connection or memory to the poems as they invite reader comparisons to their own work experiences:

Your job is to take the cement
grey-green, ugly, utilitarian, dusty and not just dusty but poisonous, abrasive, blocky, sharp-edged, impossibly heavy and dangerous in slings from overheard lifts
and transform it into something else.

Pull off the present disk,
fingers fat with heavy rubber gloves,
and whack the grinder wheel s Velcro pad down onto the next one waiting;

Shift is a collection of poems that leave an indelible mark that we humans are interconnected and that we are intrinsically bound to the natural world. They are poems that champion the beauty and resilience of nature and remind us that we need to protect our relationships with it.
