The novel “Contact” by D. Rebbitt was published for the first time in 2017. It’s the second book in The Globur Incursion series and is a prequel to “Fulcrum”.
Captain Blount is about to go on leave and so are many of his crew when he’s urgently summoned and given command of a mission to the X5682 system. A team of scientists exploring that system activated a protocol connected to the possible discovery of alien traces.
A small fleet commanded by Captain Blount is sent to the X5682 system with a team of Marines. The alleged alien traces don’t seem convincing and in the past, such discoveries proved to be of natural origin. However, when one of the Marines ventures into a cave and finds something that is certainly not natural, the situation changes radically.
