Contains poems that look at the layers of the pasts which create a life, of the sources of self and creativity, of the structures beneath the surface. While the poems portray the sense of incompleteness, the shadow that loss casts, a later sequence suggests how the missing pieces may be recovered from the depths. The glowing, painterly poems of Jenny Lewis's first collection take soundings in the depths: of the layers of the pasts that create a life, of the sources of self and creativity, of the structures beneath the surface. It is a region of loss and of recovery, the realm where memories are stored and poetry is made. Ghosts appear. An unknown father, the 'young South Wales Borderer' who died when Lewis was a few months old, bequeaths an irrecoverable sense of incompleteness to his child. Poems about being sent away to a Masonic school, aged seven, reflect the shadow that loss casts, while a later sequence suggests how the missing pieces may be recovered from the depths. Fathom is an intense and textured collection that leads the reader from surfaces to the heart of things. In the end is a sense of affirmation, where self is made whole.
