Oliver Marsh has been building crosswords for seven years, and he's always assumed nobody was really looking.Then came the email. Every Monday, 11:47 a.m., one line, no name:Completed.Just a single letter for a signature: V.For six months, Oliver made the puzzles harder. V finished them faster. So Oliver made a different kind of decision — and buried a message inside his weekly grid, visible only to someone who knew exactly where to look.Find me if you're good enough.Amelia Voss found it on the second read-through.A structural engineer with a sharp eye for hidden patterns and a competitive streak she doesn't bother to hide, Amelia has been solving Oliver's puzzles every Monday morning like clockwork. Finding a secret message embedded in the grid? That's not a surprise. Finding herself genuinely curious about the man who put it there? That's new.What starts as a hand-drawn puzzle duel in the public library becomes something neither of them planned for: accidental coffee meetings that run too long, honest conversations on a riverbank in February, and a city-wide crossword tournament that forces two people who are better at building structures than talking about feelings into the same team — and the same corner of every room.Oliver has spent eight years making sure no one could take anything from him by leaving. Amelia has spent just as long not assuming a load path is there until she's verified it herself. They are, in the language they've both been quietly learning, exactly each other's kind of problem.A clean, witty, slow-burn romance for readers who like their love stories the way they like their best puzzles — layered, precise, and worth every second it takes to solve.Start reading with Look Inside — the first chapter is waiting.
