Ghost Assets! is the second book in the military-style action-adventure series Trinity Operation Novels, written by Shane Twede. This book follows the story of Cougar as he and his elite Black Ops team Trinity are tasked with locating priceless Colombian artifacts which have mysteriously gone missing. While attempting to calm tensions between Colombia and the US, whom Colombia view as responsible for the disappearance, a recently restored C-47 vanishes at sea with its two pilots. Amelia, one of the pilot’s daughters, is adamant that her father isn’t dead – and as Cougar continues his investigation, these two seemingly unconnected cases appear to be linked. When Amelia goes missing too, time begins to run out. Torn between two missions and served an ultimatum by the Colombian government, Cougar must use all of his skills to save Amelia, find the missing treasures, and not wind up the victim of the unknown enemies now on his tail.
