Love You in the Dark by Aria Cole

Jade Fletcher lives by two rules: always throw the first punch and never let a man get under your skin. As a family lawyer, she’s used to putting her heart on the line for her clients, but when it comes to love affairs, she’s a first-class failure.
Paramedic Maverick Cooper has two regrets: the night he didn’t kiss his high school crush when he had the chance, and later that same night when he let her walk away, lost to his memories forever.
But just when they’re ready to retire their hearts for good, one wild ride in a dark elevator changes everything.
