If you had to pitch your book based on its heart and theme, what would you say? For example The Necromancer’s Apprentice is about grief, how we experience it, how we grow through it, and how dangerous it can be when smothered or unfelt.
Hm... Blessed Days is about how parenting can be just as important and impactful as any of the superpowers we daydream about and it's also about the shared humanity in us all, how facing one's own demons can open pathways to each other with understanding and compassion.
The Element of Rebellion is about being strong enough to make choices in life that can push you forward for the better. It's also got themes of forgiveness, owning those choices, and willing to walk away from them if they aren't healthy for you and those around you.
