Storm's Break is one of Richard Castle's very successful Derrick Storm novels, written by Castle in the years before he met Beckett. Although referenced in the show, unlike some other Storm books, it has never been made available in the real world.
(from richardcastle.net) A brutal cold snap has practically brought Manhattan to its knees, driving the island’s denizens indoors. The city’s homeless are driven down, into the bowels of ancient train tunnels and the concrete roots of skyscrapers. It’s a world of predators and prey, and when runaway teenage girls start disappearing into this underworld, Derrick Storm isn’t afraid to find out why. It doesn’t take long before Storm trips to an international human trafficking ring headed by notorious Panama kingpin Marco Juarez. Teaming up with reliable and gutsy CIA agent Clara Strike, these two race to stop one of the world’s most vile criminals before he destroys more innocent lives.
