Forensic geologist Em Hansen might finally be falling in love again. But just as shes getting closer to FBI agent Jack Sampler, he takes off on a mysterious assignment. When he doesnt return Em believes hes in trouble but only knows two things about where hes gone: Florida and killer dust. But whats the connection between the FBI and dust particles that move invisibly across the Atlantic? Risking her relationship, she goes to Florida, only to find out hes not the only person missing. A rogue scientist researching dust has also vanished-and all the signs point to foul play. Em gets a crash course in the science of dust and quickly learns theres more to the mystery than meets the eye. Two missing men are only the beginning in a larger plot of drug smugglers and global terrorism that threatens countless lives. Truth, like dust, is hidden to the naked eye, and Em must use all the tools of geology to look beneath the surface to find her boyfriend and prevent a depraved attack before its too late.
