Summary
Natasha Romanoff doesn’t do libraries. She definitely doesn’t do Hydra science files, missing memories, or brilliant scientists who steal experimental weapons and kiss her in burning buildings.
Jemma Simmons is not supposed to be anywhere near an active Hydra operation. She certainly isn’t supposed to be the only person standing between Natasha and a buried trigger sequence in her own mind.
Now the two women are caught in a conspiracy that reaches far deeper than either expected. With Hydra embedded inside S.H.I.E.L.D., Jemma and Natasha find themselves building something the agency was never supposed to have: a secret ghost cell operating completely outside the compromised chain of command.
A former assassin. A brilliant scientist. A pilot who officially doesn't exist. A covert operative buried deep undercover. A hacker the agency can't find. A billionaire engineer hiding impossible technology behind a European charity.
Fury calls it a solution.
Jemma calls it an elegant system.
Natasha calls it theirs.
And Hydra is about to discover exactly what happens when the people hunting the hunters stop playing by the rules.
