Author's note:

Here is the sequel to Second Chance at a Family. You don't necessarily need to read it first.

This chapter is JUST an overview of what happened in Second Chance at a Family. I will post Chapter One in about 12 hours.

Clint Barton and Natasha Romanoff had a baby girl. Due to their circumstances and the dangerous jobs they both undertook, they decided to give their little girl up for adoption. Her name was Kristina. When Kristina was only three years old, her adoptive parents-carefully selected by SHIELD's top assassins-died in a car crash, raising the question of whether or not Clint or Natasha would step up and raise her. However, neither of them did. Years later, when Kristina was nine years old, she got determined to find her parents and in her methods drew a lot of attention to herself, such as managing to hire a dodgy private investigator. As she started at such a young age, she was putting herself in a lot of danger. S.H.I.E.L.D. decided to pick her up for her own protection, so they could get to the bottom of the young girl's motivation, steer her away from locating her real parents-who did not want to be found-and hopefully find her a good family with whom to live. However, upon seeing his daughter within reaching distance and knowing that she was currently in between homes, Clint decided to step forward as her father. After Clint had thoroughly questioned Kristina, for the records, they were finally properly reconnected as father and daughter, and Clint took time off from S.H.I.E.L.D. and the Avengers so that he could focus on her and give her the stable life she deserved. Clint and Kristina got on well, daughtership coming natural to Kristina while fatherhood taking a little more trial-and-error for him. He did call Agent Hill a few times for advice, and, once he had gone past his limit, he reconnected with his ex-wife, Bobbi Morse. Bobbi served as a close friend to Clint who answered all of his questions about children and girls and helped him when he was in a bit of a pickle, having had a normal childhood in comparison to his. Meanwhile, Clint remained in contact with Natasha, who remained obstinate in her conviction that she wanted no involvement in Kristina's life and that any deviance from that would only put her in danger. After a mission brought her to his house where she accidentally came face-to-face with Kristina, Natasha knew things were suddenly more complicated. In the light of some advice from Steve, she returned tentatively to the Barton household. Clint gave Natasha an ultimatum; either commit to being a part of Kristina's life fully, or not at all-She chose the former. However, never one to settle down, Natasha left in the middle of the night for a mission without considering the emotional consequences for Kristina when she woke to find her mother gone. When Natasha finally did return, she helped Clint send Kristina to her first day of school before they were both called away on what was supposed to be a quick, emergency mission with the Avengers to recover Loki's scepter. During this mission against the Hydra compound, Clint was gravely injured and transported to Avengers Tower for placement in Dr. Cho's machine while Natasha left to pick up Kristina from school. On the journey to the Avengers Tower, Natasha couldn't help but think-even under the circumstances-that this was her second chance at having a family with Clint and Kristina.
