Summary
When Alex Langdon completed a crisis intervention training at Firehouse 51, she didn’t expect to run into her childhood best friend Kelly Severide. Even less did she expect to fall so quickly for his friend and coworker, Lieutenant Matt Casey.
Alex is used to directing first responders through high-stakes crises, but when her ex-husband—the mayor of Chicago—drops their boys on her doorstep and disappears into the shadows of his own political scandals, Alex finds herself in a crisis she can’t control.
Can she trust Severide to stay the friend she remembers while she builds something new with Casey? Can she protect her sons while uncovering what her ex has gotten himself into? And when the danger turns personal, can she finally rely on the very people she’s spent her career guiding through other people’s emergencies to get her out alive?
Or will the weight of friendship, love, and secrets prove to be the very thing that buries her alive?

Summary
The man in charge stands there tall, calmly, hands crossed behind his back nonchalantly, staring ahead. Several large, burly men cross over from the other side of the room.
They start going around to everyone, one by one, peering at their faces.
“Him.
Him.
Definitely him.
Not him.
All of the girls.
Too small.
Eh, he’ll do.
So will him.
And him.”
“Beautiful.” The man in charge eyes all of their unconscious forms with a pleased look. “Let’s get to work with them. Get the truck.”
Whump. Lots and lots of Whump. Mostly Otis.

Summary
Kelly is glad Stella is going out for a girls' night with Sylvie while he is away at the arson program, even though it means his phone will be quiet for the evening. But when the quiet is broken by a frantic Violet calling to say Kidd and Brett are missing, Severide does the only thing he can: he calls Matt Casey and catches the first flight home to meet him in Chicago. They're going to get their girls back, no matter what it takes.
Meanwhile, Sylvie and Stella find themselves hostages in a battle that is so much bigger than themselves.
Read AN for trigger warnings.
