Michelle Gagnon. The Gatekeeper (2009) 409 pp. [pbo]
Publishers description: From the moment sixteen-year-old Madison Grant is abducted, an unthinkable terrorist plot is set in motion—pitting Special Agent Kelly Jones against her most powerful adversary yet. The kidnappers ransom demands arent monetary...they come at a cost that no American can afford to pay. As Kellys fiancé, Jake Riley, races to find Madison, Kelly is assigned to another disturbing case: the murder and dismemberment of a senator. At first the two cases dont appear to be related. But as Kelly navigates her way through the darkest communities of America—from skinheads to biker gangs to border militias—she discovers a horrible truth. A shadowy figure who calls himself The Gatekeeper is uniting hate groups, opening the door to the worst homegrown attack in American history.
Setting: Arizona, Texas, San Diego, Livermore, Suisun Bay, etc.
