When the military's largest space fleet disappears with a single terrifying transmission, the best and brightest are recruited to find out what happened.
Beka Grales, a young quantum entanglement expert whose only sister was stationed on the missing fleet, struggles along with her team to decipher their only clues: the encrypted memories of the lost soldiers.
Meanwhile across the galaxy, two young twin girls awaken from visions of ghastly souls pleading for help. Night after night the girls are drawn deeper into their dreams as they communicate with these lost beings. As their mother, Cam Dowager, realizes the lost souls are connected to the missing fleet, she works frantically to hide the twins and their knowledge from the increasingly desperate military.
Despite the military's sole focus on recovering their ships, Beka and Cam begin to realize the horrifying truththat the Fleet, and the creature that has taken control of it, must never be found again.
