Lena and Luka’s friend Sam is as chirpy as a songbird in sunshine.

But one day, Sam’s smile turns upside down. He’s moving far away!

Lena and Luka promise to visit, but flying is expensive. Will they ever see Sam again?

Maybe they need something scaly and wide-winged, with room enough for three…

From the author and illustrator team behind the much loved Unicorn! and Mermaid! comes a fiery new adventure about friends who can overcome anything - with a big wish and a little help from an accident-prone dragon.
