Worthy of Life

Carolina Strenor, a girl, a remarkable person, who is completely unremarkable. I know, the terms are negating, but it is true. She has a almost limitless amount of knowledge, and all she is seen for is her flawless beauty. That was all she would ever be known for if it wasn't for SHEILD, a secret government agency who created the Avengers program. A team that she is recruited for after the mess with Ultron.
The team thought that they would have time to train the new recruits, but they were wrong. After a foreign being is informed of the technologies that saved Phil Coulson and Pietro Maxinoff, and the traces of an infinity stone, the Earth is yet again threatened. With the help of Carolina, can the Avengers, both new and old, save the Earth, or will this be the last fight that humans can put up?
