"A love story stitched across time and war, shaped by the power of books. In the heart of World War II, Tom and Ben became lovers. Brought together by a secret project designed to hide British targets from German radar, the two founded a love that could not be revealed. When the project went wrong, Tom and Ben vanished into nothingness, presumed dead. Their bodies were never found. Now the two are lost in time, hunting each other across decades, leaving clues in books of poetry and trying to make their desperate time lines overlap"--Back cover.
