Suh recruits 1,000 people for an expedition to the planet, including wealthy marketing executive Cillian Mackenzie (Mac), Suh's son Lee Hak-Kun, and Ren as the chief 3-D printer engineer. Suh is deeply changed upon awakening, and writes down the location of a planet from which she claims God is calling to her. While they hike in the Alps, Suh eats a seed from an unidentified plant and falls into a coma.

They become fast friends, and Ren falls in love with Suh. Twenty years before the beginning of the novel, Renata Ghali (Ren) befriends Lee Suh-Mi (Suh) when both women intend to rent the same apartment in Paris.

Planetfall takes place an unspecific number of years into the future. The Planetfall series was nominated for the 2020 Hugo Award for Best Series. It was generally well received by critics, and was shortlisted for the 2016 Gaylactic Spectrum Award for best novel. The novel is the first book in Newman's four-book Planetfall series, which she said can be read in any order. Writing in 'Newfound Futures', Caroline Koegler said Planetfall utilizes 'exile from earth' and 'planetary exile' science fiction tropes. Planetfall was Newman's first science fiction novel and is about a 3D printer engineer in a colony on a remote planet inhabited by a large bio-mechanical alien structure called 'God's City'. An audio edition of the book, narrated by Newman, was published in the United States by Blackstone Audio in November 2015, and in the United Kingdom by Orion Publishing in December 2017. It was first published in the United States as a paperback original in November 2015 by Roc Books, and in the United Kingdom by Gollancz in paperback in February 2018. Planetfall is a 2015 science fiction novel by British writer Emma Newman.
