The day of the accident, Jess is in the backyard with a chainsaw, clearing space to build the greenhouse she's always wanted. And, as always, she is thinking of Arthur. Arthur, her colleague in the botany department, who never believed she'd actually start the project. Arthur, who has cut off contact, escaping to the subarctic to study the pines. But now there has been a disaster, connected to Jess's husband's space tourism business: the explosion of a shuttle filled with commercial passengers, igniting a media frenzy on her family's doorstep. Jess's engineer husband is implicated, and she knows there is information he's withholding from her, even as the cameras turn to her for answers. Struggling, Jess writes to the only person she can be candid with. She writes to Arthur. And in her emails, freighted with longing, regret, and the old habits of seduction, she tries to untangle how her life has changed in one instant, but also slowly, and how it might change still.
