Agent Ward, meet Agent Jones.

Brynn Jones had an interesting childhood. She spent years knowing of Torchwood and wondering who her mother was but loved her father, Ianto Jones. When introduced to Torchwood Three, Brynn is dragged into the universe and its problems, doing her best to fix what she can.
Now, she works with SHIELD but not for SHIELD. She never works for anyone, just with them. Alongside Ward, Simmons, Fitz, Coulson, Skye, and May, Brynn makes a dent in the alien world just like her family did before her.

(A/N: this is a Torchwood AU, no one dies but Jack (because that's what he does). It strays into a few other fandoms but focuses on Brynn and her adventures. Either before SHIELD or during SHIELD)
