“Love, as I hope you will find, has great power. Even death cannot destroy it.”
ibid
Drenai series, Waylander II: In the Realm of the Wolf
Context: One day you'll find a love, and then we can talk on equal terms. I do not mean that to sound patronizing. You are bright and intelligent. You have courage and wit. But sometimes, it is like trying to describe colors to a blind man. Love, as I hope you will find, has great power. Even death cannot destroy it. And I still love her.
