Sage Sails the World: A Little Girl’s Journey across The Great Barrier Reef is the second book in Diamond Spratling’s climate-adventure series, illustrated by Amna Zaki of The Rainbow Stories. Seven-year-old Sage and her dog Benji sail to Australia to see the reef her grandmother described, and find the coral bleached and the fish gone. Sketched in Procreate, painted by hand, and delivered print-ready to Amazon KDP.
Grandma Jean’s bedtime story is about her own trip to Australia, where she swam the Great Barrier Reef and saw sea life of every colour — even a shark. So Sage and Benji go to see it for themselves: a long flight, then a boat across open water past dolphins, flying fish and a rainbow.
They put on snorkel gear and meet their guide, Kai. There is nothing there. No fish, no coral, no seaweed — just grey rocks. Kai explains that the water has grown too warm, that this is coral bleaching, and that the fish have lost their homes.
Sage’s answer is to tell everyone. She calls her friends one by one, starting with Zoey and Mateo: turn off lights, plant trees, ride your bike, pick up trash before it reaches the ocean. Children everywhere join in. The water cools, the coral takes its colour back, and the fish swim home. The book ends on a question: Now… where to next?

Sage Sails The World follows the same shape each time. Grandma Jean describes a place she once saw. Sage and Benji go to find it. It is not what it was, and the children do something about it. Book one went to the Arctic, looking for polar bears; this one goes to the Great Barrier Reef. Both are written by Diamond Spratling and illustrated by The Rainbow Stories, which is why the cast looks the same from one to the next.
Amna was a pleasure to work with as always. She is very fast and excellent at what she does. This is my second time working with her to do illustrations for my book and it really brings my story to life. I highly recommend Amna for your book illustrations.

Amna Zaki of The Rainbow Stories, a children’s book illustration studio in Lahore. She illustrated the first book in the series as well, which is why Sage, Benji and Grandma Jean look the same from one book to the next. Amazon credits her as illustrator on the listing.
Yes. It is book two of Sage Sails The World. Book one, Sage Sails the World: A Little Girl’s Journey Across The Arctic, takes Sage to the Arctic to look for polar bears. Both are written by Diamond Spratling and illustrated by Amna Zaki, and there is a case study for the first book on this site.
From an approved character sheet rather than from memory. The turnaround, the expression sheet and the fixed colour values made for book one are the reference for book two, so the same girl and the same dog appear in both without being redrawn from scratch. New characters in this book were designed the same way before any page was painted.
Every spread is drawn as a line sketch and approved before any colour goes down. The sketches on this page are the real ones for this book, shown beside the printed spreads they became. A change at sketch stage costs a redraw of a few lines; the same change after painting costs the whole spread.
Drawn by hand. The sketches are drawn digitally in Procreate on an iPad and painted by hand from there. Nothing in this book is generated by AI, which matters for a series, because a generated character cannot be held consistent across two books.
The author does. Copyright in the artwork transfers in full to the author on final payment, which is what lets them publish, reprint, license and sell the book without coming back to the studio. That is the standing arrangement at The Rainbow Stories on every commission.
It is published and on sale on Amazon in hardcover, as Sage Sails the World: A Little Girl’s Journey across The Great Barrier Reef, ISBN 979-8992474916. It was published on 21 February 2026.
