Kate Middleton's third poetry collection continues her preoccupation with terrestrial and other landscapes, both real and imagined. The poems haunt, and are haunted by, the legacies of literature and history: whether inhabiting the scientific laboratory, the exploratory voyage, the layered history of landscape, or the voices of past authors, they are interested in the border-zones of understanding, in both the 'the riddle of untrodden land' and the buried history of lost empires. Formally, the poems move between traditional lyric and collage-style forms of quotation and erasure. Others take a speculative turn away from the book's historical grounding, such as in the sequence of poems titled 'Watching Science Fiction' that are scattered throughout the book. Passage traces an imaginative path through orientation and disorientation, where a god in the form of a lion and rabbits with eyes 'fantastically in bloom' surprise and enchant at every turn. It observes the world under a watchful gaze, 'Patient as an avalanche.'
