"Silverworld" is a 560,000-word interactive time-travel fantasy novel by Kyle Marquis, where your choices control the story. It's entirely text-based—without graphics or sound effects—and fueled by the vast, unstoppable power of your imagination.

You need allies to survive, but who can you trust? The locals may have already betrayed you to appease their enemies. The empress back home has ordered you to plunder this new world. Your friend survived the crash only for the jungle to infect him, transforming him into something inhuman. And the expedition's chief adviser has imprisoned the Icons—architects of the universe, masters of time—and fled to build his own civilization.

Can you rebuild Doctor Sabbatine's time machine and return home? You must protect your timeline, but at what cost? And after leading the people of Silverworld, will you even want to?
