While out shopping at Sam's Club with my mom, I found something in the book section of the store that caught my eye; a 400-page, hardcover book entitled 'Black Widow: Forever Red' by Margaret Stohl.
As I read, I noticed several different things such as the involvement of Agent Phil Coulson and Tony Stark. Plus, Natasha constantly finds herself thinking of Bruce Banner and Pepper Potts, both who are also frequently used in the Marvel Cinematic Universe. Finally, there are little quotes placed in sections of the book, one of which simply reads 'Love is for children', a line I recognized almost immediately from Marvel's The Avengers, when Black Widow is trying to get Loki to tell her his plans.
Anyways, with all of that info, can anyone determine whether or not this story fits in with the MCU? If so, help would be greatly appreciated.
