As botany professor Jess Frobisher clears space in her yard to build the greenhouse she’s always wanted, her mind begins to wander. It wanders, as it always does, toward Arthur, her colleague in the botany department. Arthur, who never believed she’d actually start the greenhouse project. Arthur, who in the aftermath of their affair, has cut off contact, escaping to the subarctic to study the pines.

Jess’ mind soon snaps back to reality when she learns the space tourism business founded by her engineer husband has experienced the worst possible disaster: A space shuttle filled with commercial passengers has exploded. Jess’ husband is implicated, and she knows he is withholding information from her. As the tragedy unfolds and the investigations are launched, an increasingly isolated Jess writes to the only person she can be candid with: Arthur. This updated version of the “epistolary” novel unfolds via Jess’ emails to her former lover, freighted with longing, regret, and the old habits of seduction. And though the reader never hears from Arthur, Jess certainly does. Foster paints a vivid relationship via provocative email subject lines, unseen correspondence, and references to an intriguing past that predates the novel.
