What happens when a free book expires?

You saw a free book yesterday. Today the price is back. What actually happened — and what do you keep?

If you already downloaded it

You keep it. Once a book is in your library, the price change does not take it away. Downloading during the free window is the whole game.

If you waited

The deal is gone, but the same book often returns free later — authors repeat promotions. Watch the expiring soon page to catch the next window, and check the free library for fresh deals in the meantime.

The rule is simple: if you want it, grab it before the clock runs out. Expiring books are the ones that reward quick action.
