Iron Lines — A.J. Russell

Benjamin T. Meadows and his sister Felicity 'Fliss' Meadows have a problem. Trapped in Reykjavik along with everyone else after the Icelandic government's nuclear power plant at Echelon suffers a devastating meltdown, they worry about the effects of radiation sickness. When a veteran of the Chernobyl disaster is appointed to clean up the mess, there's only one way to cross the volcanic wilderness. Join Ben and Fliss in their adventures on the Jarnbraut Feroast - the Voyager Railway - as they attempt to reach the Echelon facility."
