Surrender Together. The Elsewhere Riddle, #3

Isador's mentor is dead, leaving Isador to wonder if he caused so much heartache on no more basis than their old enmity. He worries Pallas knew something important, something to do with Elsewhere or the Tet Ravos. He won't have time to investigate, because war with Elsewhere is imminent. Troubling questions have been raised, too, about his destiny. Danae makes a commitment that will change, not only her own life, but the course of history.
Back home, Selene joins humans in increasing numbers arguing for their right to fight alongside elves for their shared homeland. And Delephon and Calix must finally decide if they're enemies or allies. To triumph, they'll have to trust each other to surrender together.
