Craft a fantasy story that changes minds, touches hearts and impacts the world

You’re not just writing a fantasy story

You’re thinking about people, power, justice, relationships, history, and the kind of world your story imagines – and you want that to come through on the page.


I’m your book coach, Sandra Postma!

I’m a values-driven Author Accelerator certified book coach who helps fantasy writers across subgenres who want to weave real-world themes into magical stories.

I help you clarify what you’re really trying to say, strengthen how it shows up in your story, and keep moving forward with confidence without losing the magic or joy of writing.

Sandra Postma, your coach

My approach as a book coach is rooted in values and craft

• Respect for your voice and vision

• Space for complexity, nuance and questions

• Attention to both storytelling craft and emotional impact

• Support that challenges you while always keeping your vision

Stories shaped with care, not formula

In particular I help writers who:

Believe fantasy can shift perspectives, build empathy or spark change

Write fantasy in many forms (contemporary, historical, urban, steampunk, light, high, etc.)

Care about social themes (power, inequality, disability, colonialism, climate, justice, (queer) identity, social systems, history)

Want their stories to mean something to the reader, not only entertain them

WHAT MY CLIENT SAYS

“Sandra has the best insight for helping writers keep moving forward in their writing. She saw things in my writing that I was missing and knew exactly what I needed to do to improve my story structure. Above all Sandra is kind and encouraging with all of her feedback and you can just feel how much she believes in your story and in you as a writer. The combination of that belief, her passion for good stories, and her obvious knowledge and skill makes for a perfect coach! I am so glad I have had her in my story process!”

This is not about speed or productivity. It’s about building a novel that holds together and makes an impact, technically, emotionally, and thematically.

YOU MIGHT BE HERE BECAUSE…

You’re writing fantasy, but it’s never felt like “just escapism” to you.

You care deeply about people, society, and the world — and those concerns naturally find their way into your stories.

You have strong ideas, questions, or values, but you’re not interested in preaching or being heavy-handed on the page.

You want your story to mean something, without losing magic, joy, or wonder.

You sometimes wonder whether what you’re trying to say is actually coming through to a reader — or only living in your head.

You’re committed to writing the best story you can, not the fastest or most marketable one.

You want to finish your manuscript, but you don’t want to flatten it or simplify it just to get there.

You’re looking for thoughtful, professional support that respects your voice, your process, and your values.

You believe stories can change how people see the world — even in small, quiet ways.

If this resonates, we should talk!

WHO THIS IS (NOT) FOR

I’m your coach if…

  • You write fantasy and care about people, society and the world
  • You value depth, meaning and imagination in storytelling
  • You’re open to a thoughtful, collaborative process without losing control of your story
  • You’re unsure what you want to say but want to work hard to find out
  • You’re open to the discomfort that comes with writing stories that matter and the deeply honest feedback that comes with it

I’m not your coach if…

  • You want fast drafting challenges or quick formulas
  • You’re looking for affirmation and validation without being challenged
  • You’re looking for trauma-processing support
  • You don’t believe in equality, inclusion, diversity and accessibility
  • You’re not interested in the deeper meaning of your story

NOT SURE WHERE TO START?

If you want a low-commitment way to gain necessary clarity, the Mini Blueprint or First 30 Pages Feedback is a good place to begin.

If you want to build strong foundations for your novel, the 3-Month Book Blueprint is often the best next step.

If you’re committed to finishing your book and want ongoing guidance, Novel Mentorship offers deep support.

MY INVITATION TO YOU

If you’re writing fantasy because you care – about people, about the world, about the impact stories can have – I’d love to support you.

GET IN TOUCH!

Speaking with Sandra was so helpful and encouraging. She helped me identify a few actionable items I can implement immediately. She also reminded me of the importance of babysteps any time you’re trying to make a change.

The experience was all positive. I appreciated Sandra’s honesty, her compassion, her openness. I love how she reframed things for me.
