Black Widow — Lindsay Smith

Super-heroic spies must unravel a conspiracy -- and save the world -- in this original Marvel adventure.
 
Before Natasha Romanoff was an Avenger, she was a Russian spy and assassin, genetically altered by Soviet Union�"era scientists to become a super soldier. But someone has stolen a sample of her blood -- and the blood of James “Bucky” Barnes, the operative known as the Winter Soldier, another human weapon developed in a Russian laboratory.
 
Whoever took their blood possesses the key to recreating the formula flowing through Natasha and Bucky's veins -- the formula that enhanced their physiology to superhuman levels. Now, the Black Widow and the Winter Soldier must work together to track down their mysterious enemy -- even as their history as lab rats and conditioned agents brutally trained in Russia's notorious Red Room continues to haunt them . . .
 
Black Widow: Bad Blood is a collaborative novel by Lindsay Smith, Margaret Dunlap, Mikki Kendall, L.L. McKinney, and Taylor Stevens.
