Fighting the Fire by Laura Kaye

 Sean is a fireman. Daniela is a nurse. They both served, and are members of WFC. They had a thing, and now they are flirting around each other. Daniela is a widow, her husband died in action.

Sean is leaving from dinner on his motorcycle, when he is hit by a truck running a red light. Dani goes into nurse mode at the scene. Sean has an eye issue, and hurt ribs. Dani stays with him, and lets WFC know what is going on so someone can be around to help him. Sean quotes the movie Deadpool a lot, and he loves superheroes, so they have a movie marathon. Sean even makes a spreadsheet of the Marvel movies in order, but he won't tell Dani exactly how many there are. Dani gets sick, and Sean realizes he loves her and wants to take care of her.
She gets better and goes home. This is the 6th anniversary of her husband's death. She hasn't read his 'in case something happens' letter. Sean accidentally rips it and she thinks he read it. She gets upset, and he leaves. She then reads the letter and realizes Anthony wants her to find love again. She realizes it's with Sean. He doesn't answer her texts or calls. They meet up at Noah and Kristina's house for a July 4th party, talk, say 3 words, and make love in the back of her car.
Sean is matched as a Big Brother, and spend time with his friend in the last chapter. He also is all better from his accident, and goes back to firefighting. No epilogue but 3 months later they are moving in together.
