Official ABC Synopsis:
After Oceanic Air flight 815 tore apart in mid-air and crashed on a Pacific island, its survivors were forced to find inner strength they never knew they had in order to survive. But they discovered that the island holds many secrets, including a mysterious smoke monster, polar bears, a strange French woman and another group of island residents known as "The Others." The survivors have also found signs of those who came to the island before them, including a 19th century sailing ship called The Black Rock, the remains of an ancient statue, as well as bunkers belonging to the Dharma Initiative -- a group of scientific researchers who inhabited the island in the recent past.

Connection to the Show
There's a lot of Lost out there besides the show, including magazines, online games and books, but here's the bottom line: You can read all the books, visit all the websites, hunt down that box of hair colouring with Daniel Dae Kim on it, and you will understand what's going on no better than people who just watch the show.

Bad Twin
This is a real-life novel by TV-life author "Gary Troup," who supposedly died when Oceanic Flight 815 touched down on the water runway. Sawyer found the manuscript and gave it a thumbs-up, in one of the show's increasingly frequent clunky product placements – er, "innovative marketing synergies."
