The Vampire’s Song. The Last Immortal, #52

For centuries, Nico has lived as an immortal vampire with a heart he believed had stopped beating long ago. He has survived by keeping his emotions buried, convinced that loving someone only means eventually losing them. Then he meets Pavel-a mysterious vampire whose voice carries an ancient melody known as the Vampire's Song. The song is more than a legend. It is an ancient magical force capable of awakening buried emotions, breaking supernatural control, and connecting two immortal hearts.
When the ruthless Bloodbound Order discovers Pavel's gift, they intend to use him to control vampirekind. Nico refuses to let them take the man he has come to love. As Nico and Pavel uncover the truth behind the song, they discover that the prophecy surrounding it has been misunderstood for centuries. The song does not demand sacrifice. It requires two hearts willing to share their power-and two vampires brave enough to choose love despite the possibility of loss.
Together, they must face betrayal, ancient enemies, dangerous magic, and the terrifying possibility that their bond could either save vampirekind or destroy everything they know. Through battles, separation, and sacrifice, Nico discovers something he thought immortality had taken from him forever: his heart.
