These poems investigate both sacred and natural spaces. Her poems move grief and emotional suffering to language as a site of recovery and renewal. Much of this collection is ordered around the work of the Swedish visual artist Hilma af Klint. As the first artist to arguably use abstraction, her radical work brims with enigmatic botanical images painted to grasp the seemingly boundless and hermetic realm of the dead. Similarly, Jackson's poems explore plant life and natural species in the Green Mountains of Vermont, where perceived thresholds blur in acts of spiritual reimagining. This is a book that questions all that is endless, all that has been thought as limiting, and all that remains unknown.
