The Road To Blackest Night Reading Order

[ryerye17]

Okay, a friend of mine just picked up Blackest Night 1 today. And he has absolutely no idea about DC. He loved Blackest Night, he knew the characters and all, but he wants to be able to pick up the ROAD TO BLACKEST NIGHT.

I know there's GL : Agent Oragne, Sins of the Star Sapphire, BN 0, FC : Rage of the Red Lanterns, all the GLC issues, Titans 15, but what is the best chronological way of reading the ROAD TO BLACKEST NIGHT?

Thanks!
