One of the novella's greatest strengths lies in its unique premise. Egan masterfully weaves together hard science fiction elements with a compelling narrative, creating a plausible and terrifying scenario that feels all too real.

Egan's decision to focus on a small group of individuals gives the story an intimate and personal feel, even as it grapples with the larger implications of the global catastrophe.

Egan deftly touches upon issues such as migration, resource scarcity, and the varying responses of nations to the unfolding disaster. The novella's exploration of these themes feels particularly relevant in light of the ongoing discussions surrounding climate change and its potential consequences for humanity.

While some readers may find the ending abrupt or the character development lacking in certain areas, these minor shortcomings do not detract from the overall impact of the story.
