The quote from Susan Cooper's "King of Shadows" conveys a profound message about the enduring nature of love. It suggests that love remains constant, regardless of physical absence, the passage of time, or even the loss of loved ones. This implies that love transcends these barriers, continuously providing comfort and a sense of security to those who cherish it.

In essence, the passage reflects the idea that love is an everlasting bond, a sentiment that resides within us and shapes our lives. It reassures us that even in moments of loneliness or grief, the love we hold for others does not diminish but instead offers a lasting presence that supports us through our struggles.
