"Kepler...ups the ante in this pulse-pounding ninth Killer Instinct thriller featuring detective Joona Linna.... Kepler manages to make each murder resonate, giving the deaths uncommon weight in the lives of Linna and his fellow detectives, who grow increasingly distraught at their failure to prevent the killings. That veracity, combined with regular passages of almost unbearable tension, make this another standout in a strong series."
