Bestseller Connelly's dazzling 13th Harry Bosch novel (after 2006's Echo Park) reunites Bosch with his former flame, FBI agent Rachel Walling. Bosch must break in a new partner, rookie Iggy Ferras, when they're called to look into the execution of physicist Stanley Kent on a Mulholland Drive overlook. When a special FBI unit, headed by Walling, arrives and tries to usurp his case, claiming it's a matter of national security, Bosch refuses to back down. Walling's focus on the potential theft of radioactive material from the hospital where Kent was lending his expertise to cancer treatment and her unwillingness to share information only make Bosch more determined to solve the case. This is a quick read, almost half the length of Connelly's previous novels, but he spares no punches when it comes to complexity and suspense. The scramble to investigate threats to national security, justified or otherwise, is a timely subject and one on which Connelly puts a brilliant new spin.
