Lost covers diverse topics within one vibrantly illustrated book: nature, geology, astronomy, archaeology, and biology with a sprinkling of philosophy.

What does it mean to be lost? Is it stranded at sea without a map, or carefully camouflaged in the wild? Travel back in time to hear herds of honking dinosaurs, find sunken shipwreck treasure and uncover ancient cities in the sand. The things we've lost could even hold the key to protecting our future, so there's not a moment to lose. Lost worlds await.
