*Agents Liz Sherman, whose supernatural talent for starting fires killed her family when she was a teen, and Roger the Homunculus, the five-hundred-year-old artificial man who nearly killed Liz by stealing her fire, are sent to investigate a mystery train terrorizing America. This is a train with history--its last natural journey, some seventy years ago, had a mysterious passenger on board--Lobster Johnson, who's still bound to the fate of the locomotive. *Source: darkhorse.com
