The Moonday Letters

Sol has vanished. Lumi, their wife, was born on Earth, and she sets out to learn what happened. Every clue she follows opens onto another question.

The trail leads to underground environmental groups and to a tangle of secrets that stretches between the planets. Lumi travels from the wealthy colonies of Mars to what remains of a devastated Earth. Along the way she digs into Sol's past, and into long-forgotten secrets of her own.

The book is a mystery and a love story between two people from very different worlds. It mixes space-age science fiction with eco-thriller, and it tells its story through letters and extracts, so the reader pieces the case together from documents as Lumi does.

The tone is literary rather than action-driven, with myth and science woven into the search. Expect a puzzle that deepens with each step, and a relationship that is as much the subject as the disappearance.
