The CIA doesn’t know what to make of the old wreckage of a domed container, possibly a cargo pod. Someone unearthed it near the Nevada Test Site, making communist-hating America fear the Russians have been up to no good. Answers may lie with a metal disk found inside the container and with four sets of coordinates marking areas surrounding the wreckage. Dr. Frank Sartori of the Atomic Energy Commission scours Western desert landscapes for each location. What he discovers sparks wild theories, such as the pod is extraterrestrial and carried a now-missing passenger. But it’s the strange symbols on the disk that the physicist finds truly spellbinding. They’re identical to the ones on the aluminum attaché case of his uncle, the man who raised him and cryptically asserted that they both were “not of this world.” Working with Bob “Bobcat” Babcock, a member of the Army Corps of Engineers, Sartori aims to unravel the mysteries of the pod, which is seemingly capable of creating energy from magnetic fields, and deciphering his bizarre link to it. Costanzo’s story deftly drops assorted puzzles at Sartori’s feet. Along with his AEC investigation, he must deal with his dreams, which teem with inexplicable images (for example, an unknown man at a bus stop), and his uncle’s abrupt disappearance. The tale is generally easygoing, as the protagonist doesn’t face sinister forces. But he does struggle to trust people, even immensely likable Bobcat and a local newspaper reporter named Kate Wilson who doubles as a potential romantic interest. The author couples a measured pace with vibrant prose, such as nuclear tests producing “a glowing orange sphere inside of an iridescent, billowing gray cloud.” Costanzo also aptly infuses real life into the narrative, from people constantly worrying about atomic bombs and radiation to characters mentioning famous baseball teams and players and TV series. The superb ending resolves some of the questions that readers will be asking.
