My novel-in-editing, Unnatural Causes, is a murder mystery: the death of a prominent and controversial mage by her apprentice and familiar. The familiars in this world are extraplanar beings, and their status is uncertain: indentured servants at best, slaves at worst. I put two themesongs in my notes to play off their attitudes towards the world around them. The first is hard, driving and rebellious:
Are We All We Are - P!nk
It also has some relevance to narrator Vil, who personally is defiant and impatient.
The second is more aspirational, a hope for peace:
The War Is Over - Sarah Brightman
But with their future in doubt, their primary advocate murdered, what truly is in store for the familiars?
