“The Vanished” may be book 9 of the Robert Spires series but it is an excellent read as a stand alone novel. It begins with Vanessa and Stefan hiking in the Great Smoky Mountains as what begins as a hiking adventure ends with Stefan’s disappearance. This event is just the latest in similar disappearances that have been occurring in the area so the UK’s Global Environmental Command, GLENCOM for short, dispatches Robert and Agent Belinda Caruso to investigate since it is thought that they might have some environmental connections. Along with the disappearances, for decades now, there have been cases of  cattle and other livestock mutilations in neighboring farms that look as if they were done by scalpel or laser technology. No tracks or other evidence as to who might be responsible for the unexplained deaths has ever been found but there might be reason to believe that there might be an extraterrestrial link since there have also been instances of unusual lights in the night sky. Robert Spire and Agent Belinda Caruso team up with Spire’s old friend, ex-U.S. Marine Travis Dexter and the deeper they dig, the clearer it becomes that the U.S Military might be involved.

While the topics of farm animal mutilations, missing hikers, and mysterious lights in the sky are common occurrences in the real world, the author brilliantly combines them to create an intriguing yet unnerving science fiction adventure. Far from giving clear explanations for them, he does give a possible, though chilling, reason for the disappearances that could very well happen and leaves the way open for expanding on this story, including which mysterious government agency may be involved. It also serves as a warning to humanity without coming off as preachy or condescending. The characters are believable and relatable, but giving the assassins for hire brothers the stereotypical ‘Deliverance-like’ characteristics makes them seem cartoonish at most. The language is easy to follow and understand and makes the story flow naturally. Overall, it is a must-read and thrilling science fiction novel and is recommended for readers who enjoy science fiction, UFO/alien stories and appreciate speculative fiction.
