Crescendo - Song of the Fallen, #2

Bridging the hatred of centuries did not come easy for Freyrík Farr and Ayden Vaska. As prince of a war-torn human province, Freyrík could ill afford to fall for an enemy. And Ayden, an elven warrior with three hundred years of bitterness in his heart, wanted no part of love. Yet they came together despite themselves and the wills of their peoples, joining hearts and minds to fight a race of Dark Beasts threatening the extinction of mankind.
Yet the Dark Beast threat pales beside the dangers of a summons to the human High Court, home of the Aegis Exalted and the harshest test yet of Ayden's and Freyrík's fledgling love. When the Aegis strips Ayden of his magic, Freyrík is forced to choose between his love for elf, Aegis, and king, all the while seeking the one uncertain path that might save his doomed race. Time is fast running out for mankind, and only by making peace amongst themselves and with their ancient elven enemies can they end the Dark war-and undo the tragedy that's plagued humans, elves, and Dark Beasts alike for the last three hundred years.(This title is a lightly revised second edition of Crescendo, previously released with a different press.)
