If I Should Die by Amy Plum

If I Should Die delivers a stunning, deeply satisfying conclusion to the international bestselling Die for Me trilogy by Amy Plum.
 
Kate is devastated. Her boyfriend Vincent is a revenant who waited lifetimes to find her. But once he did their future together was shattered almost immediately. They were betrayed by their trusted ally, Violette. She killed Vincent and destroyed his body so that he could not be reanimated.
 
Now Vincent is doomed to roam the earth as a spirit. But Kate isn’t willing to accept life without her true love. She’ll risk anything to save him, even as Violette, their friend-turned-enemy, begins to wage a war to rule over France’s Immortals.
 
Amy Plum created an intricate, original mythology for her YA paranormal series. The books, set in Paris, the City of Lights, introduce readers to revenants, undead beings who must sacrifice themselves again and again to save the lives of strangers.
