How does the story end? Does Ever and Danem live together/stay together? Did Drina die?

In Chapter Thirty-seven, Ever goes to the kitchen for ice cream and finds Drina. Drina reveals that she's been hunting down Ever repeatedly for six-hundred years. She then reveals that she'd sent that deer into the path of Ever's family's vehicle, knowing Ever's dad would dodge and wreck. Drina tells Ever she should simply give up her life and join her family.

In Chapter Thirty-eight, Ever is relieved of her guilt over her parents' deaths and that gives her power she never had before. In the fight, Ever suddenly realizes she's going to lose but then strikes out and Drina falls. Damen is then in the room as Drina ages and disappears. He says Ever's love and Drina's hatred combined to become Drina's demise. Damen warns again that joining him means she'll never cross the bridge to join her family. Ever says she loves him and he says he has always loved her.
