Writing fantasy books

Magic is real, and it costs something.

Fantasy builds a world where the impossible works: dragons, spells, gods who answer back. It might be a whole invented continent or one enchanted door in an ordinary house. Either way, readers come for the wonder and stay for the people paying the price for it.

What readers expect

  • Magic or the supernatural, with limits
  • A world that feels lived in
  • Quests, wars or a power worth fighting over
  • Myths and history under the surface

A tip before you start

Give magic a cost. Readers believe in a power when they can see what it takes from the person using it.
