Is it your wish to be a science fiction or fantasy writer? Do you want to develop a sci-fi or fantasy story?

Would you love to explore your story’s world, but are you unsure what your voice is or what exactly you want to say with your story?

Or do you have a fantasy or sci-fi manuscript and desire personal feedback?

Do you happen to have a chronic illness that impacts your daily life?

Do any of these apply to you? Then I am the book coach for you!

Hi! I’m Sandra Postma (she/her) and I’m a writer and a certified book coach. I have also been a spoonie for over two decades.

As an Author Accelerator certified book coach I help sci-fi and fantasy writers build their story idea into a ‘blueprint for a book’ (as developed by my mentor Jennie Nash) while working on their writer’s mindset so they start writing their book with a solid foundation for the story and the confidence to keep writing.

My superpower as a book coach lies in my empathetic approach of speculative fiction writers who have trouble believing in their own story and writing abilities.

I coach you from a place of kindness, encouragement and empathy gained through my own life as a spoonie combined with my expertise and knowledge of storytelling and the craft of writing. I mentor you as a person as well as a writer!

As a spoonie, I specialise in helping writers with chronic illness navigate the complicated emotions and thoughts that come with our conditions while building that same story foundation. Being part of the spoonie community, I know the specific struggles and extra challenges that come with combining a wish to write with your personal health situation. Having someone there with you to carry the story load might be just the thing you need to write.

Because I believe in the transformative power of sci-fi and fantasy, I love helping writers dig deep into themselves to write stories that are rooted in their own beliefs and perspectives, stories that contain important messages for readers and our society as a whole and stories that mean something to the writer. As your book coach, I help you find these values and messages and help you shape your stories in a way that is true to you.

Lastly, as I love helping writers write the best story they can, I offer deeply personalised manuscript feedback. Before diving in to see where your book could be better, I first talk to you to find out what your goals and hopes are for your story and how you feel you achieved that in your manuscript. Then I dive in and focus on those doubts, hopes and goals, before coming back to you with my honest feedback, after which we will once again talk and I help you establish clear next steps for your story to become the best it can be.

Does having an empathetic professional or a fellow spoonie in your corner who helps you as you develop or revise your book speak to you?

Then check my 1:1 services, my group coaching program as part of the Spoonie Writer Academy or my manuscript feedback service and tell me about you and your story (idea)!

I launched the Spoonie Writer Academy – or Spoonie Writers Club elsewhere – because as a writer and book coach with a chronic illness I felt alone in my particular struggles with writing.

A low energy basis and a whole array of daily symptoms, plus the mental struggles that come with a life of illness, comes with its specific set of challenges that combined with a lack of visibility in the publishing industry, and society as a whole, made me feel compelled as a book coach to focus on writers like me and create a space to come together and share our specific experiences.

Follow and engage with the Spoonie Writer Academy on Instagram or join in by signing up to its group coaching program! Because you are not alone, our voices are worthy of being heard and our stories of being told.

I am the right book coach for you if…

  • …you feel a little (or a lot!) insecure about your writing
  • …you lack the confidence to talk about or share your ideas
  • …you even struggle to call yourself a writer
  • …you want to dive further into your story idea and really find the heart of it
  • …your values and beliefs are important to you
  • …you are part of the LGBTQIA community, or are an active ally
  • …you are a spoonie or struggle with mental health issues, such as anxiety or depression
  • …you are invested in your story and ready to invest in yourself too – or at least desperate to wanting that be the case!
  • …you value kindness, empathy and honesty

I know the feeling of not seeing yourself in the culture and art you consume. It feels as if your story doesn’t matter.

It also shows us the immense power storytelling can have when such voices do get to tell their stories.

I see the impact it has on people’s confidence to be able to tell their story in a safe setting. In turn their stories have a direct impact on our society.

All our voices deserve to be heard. We all deserve to feel seen. YOUR novel deserves a place in the world too!

MANUSCRIPT FEEDBACK: personal attention and feedback
Do you need 1:1 help with pinpointing where you can strengthen your full, final manuscript? Are you not getting the responses from agents or publishers you were hoping for? See a problem but don’t know how to fix it? Then in-depth feedback from me as a professional book coach might be exactly what you need in order to make your story even stronger than it is!

Sandra is a talented and attentive mentor who knows how to put writers at their ease, and fosters a safe environment where even the most fragile writing stages are nurtured and encouraged into growth. I had a wonderful time working with her.”

Clio Velentza, author of “The Piano Room” (Fairlight Books, 2021)

“I cannot thank Sandra enough for her thorough and thoughtful evaluation of my manuscript. Her balance of honest praise and compassionate critique helped me see what I was doing well and what needed attention. She provided clear steps on how to move forward with my final revision. Her feedback on my query letter and synopsis was incredibly insightful. I was blown away at her dedication and the quality of research she did for my agent pitch package. I cannot recommend her coaching services enough.”

Stacy Frazer, YA fantasy author and book coach
