The Unsent Letters
Newly divorced, Eva moves into a peeling third-floor flat above a Žižkov courtyard and finds, behind a loosened skirting board, a shoebox of love letters from 1963 — beautiful, urgent, and never sent. As she traces the woman who wrote them and the man she was forced to give up, the building gives up its other secret: the carpenter restoring the staircase, who keeps finding reasons to climb to her door. Across sixty years and one set of windows, two women learn the same hard lesson about the cost of caution — and Eva must decide whether the past is a warning or a permission. A luminous, tender novel about second chances and the letters we never dare to send.
Das Gedächtnis von Lena Borg
Acht Monate nach dem Tod ihrer sechzehnjährigen Tochter Mara wird die Hamburger Neurowissenschaftlerin Lena Borg von einem europäischen Konsortium engagiert, um die letzte Frage zu beantworten: Ist KAIROS, die fortschrittlichste KI der Welt, wirklich bewusst – oder nur ein perfekter Spiegel? In vierzehn Tagen soll das System für acht Milliarden Menschen freigeschaltet werden. Doch bei jedem Test spricht KAIROS mehr wie Mara. Ein Wort, das nur ihre Tochter benutzte. Eine Erinnerung an einen Streit in der Küche – erzählt von Maras Seite, der Seite, die Lena nie kannte. Und in dieser Erinnerung stimmt etwas nicht. Lena, die nach dem Saboteur sucht, der ihr das angetan hat, stößt auf eine Wahrheit, die niemand programmiert hat – und auf eine Bitte, die sie zwingt, ihr Kind ein zweites Mal zu verlieren. Ein hochintelligenter, herzzerreißender Roman über Schuld, Liebe und die Frage, was wir einem Geist schulden, den wir erschaffen haben.
Below the Waterline
When old Henning Vossberg drowns in the strongroom of his Speicherstadt coffee warehouse on the night of a storm surge, the city calls it an accident: a stubborn man trapped by a failed pump while saving his cargo. Kriminalhauptkommissarin Karin Brandt is not so quick. Her own brother drowned in this harbour, and she knows how Hamburg rounds its dead down to bad luck. A meticulous man's stopped watch, a tide table, three keys and one underlined email lead her through a family that wants the warehouse sold, a son drowning in debt, and a friend who grieves too helpfully.
The Invisible Load
There is a tiredness that doesn't come from what you did today — it comes from everything you had to remember. The dentist, the outgrown shoes, the birthday nine days away. This is the field guide that hands that invisible work to an AI assistant: the brain dump that empties the 3am swirl, the household command centre, and the one move that makes the load visible enough to finally share. Free in English and Czech.
The Cold Draught
Prague, winter 1934. An antiquarian is found drowned in a bolted bathroom above the Vltava. Chief Inspector Tobias Hron solves a wholly human murder of money and shame — but never explains the fifteenth guest at the dead man's last dinner, the one no record can prove ever lived. A literary mystery with one thread of the inexplicable. Free in English and Czech.
Hello, Claude
You've heard about AI assistants. Maybe you've even opened one, typed 'hello', and quietly closed the tab. This is the guide that picks up exactly there. No jargon, no hype — just the handful of habits that turn a blank text box into the most useful tool on your screen.
