Cold Blood by Cynthia Rayne

Time can’t heal wounds, but love does.
Justice is a biker and former Navy SEAL living with PTSD. While he didn’t give “the last full measure of devotion” to his country, he came damn close And his nightmares drag him back to Afghanistan.
Etta May Jameson is a social worker dealing with her own painful memories, but she’s attracted to Justice. Her boundaries are crumbling and she longs to take another chance on love. They need to deal with their battle scars as well as they’re growing feelings.
But when Etta’s ex-husband is paroled, her past becomes present. And her future is in jeopardy.
