Nicholas Keegan and Aleksandr Zorin are back in this second installment of the Chaos series by D.J. Schuette, but it's FBI New-Agent-in-Training Addison Lange who takes center stage in Maelstrom. Using her inimitable coding and hacking skills, honed through a decade of grief and guilt, Addie embarks on one final, desperate search for her brother, Tommy, who disappeared from their front yard in 2006. Meanwhile, FBI profiler Nicholas Keegan deals with the devastating consequences of his confrontation with Aleksandr Zorin in the only way he knows how and ends up the prime suspect in a murder he can't remember committing. A third thread finds us back in August of 2016, bearing witness to the culmination of Connie Keegan's encounter with Zorin. As these three plotlines merge, we'll be propelled to an unfathomable and explosive conclusion that will decide all of their futures.
