What’s it about?

The story.

On the Island of Ayrie, Tilda knows everyone and everything: the roads, the hills, the tides, the stories and the summer bonfires for the migrating puffins. She loves the island exactly as it is and does not want anything to change. But change comes anyway, forcing Tilda to face what it means to belong to a place, share it with others and carry home in her heart even when the familiar shifts. Katya Balen brings her usual sensitivity to landscape, community and child emotion, shaping an island story that feels wild but grounded. Ghostlines is less obviously heavy than some of Balen's family-conflict novels, but it still has emotional complexity around friendship, newcomers, community and resistance to change. It is a good bridge between nature adventure and literary middle-grade realism.

Why it lands

Why they love it.

Why kids love it

The specific weight is Tilda not wanting anything to change — knowing every road and tide and bonfire on the Island of Ayrie, newcomers arriving, the migrating puffins still coming back and the island shifting around her. The Katya Balen for a thoughtful reader who's resisting change in their own life.

  • Animal companions
  • Friendship and belonging
  • Family belonging
  • Adventure and freedom

Why parents love it

The Katya Balen island novel — less family-conflict heavy than her previous books, more about belonging-to-place and community-shifting, puffins and tides as the constants. Strong bridge between nature adventure and literary middle-grade realism. Beautifully observed.

  • Great writing
  • Conversation starter
  • Beautiful illustrations
  • Educational for adult too
