A Peek into the Process of One Turtle’s Last Straw Illustrator Marta Álvarez Miguéns 

By Elisa Boxer

Three years ago, as I watched this video of marine biologists pulling a plastic straw out of a sea turtle’s nose, my first thought was: This has to be a children’s book! 

On shelves Tuesday, May 10, 2022!

My second thought was: This is waaaay too graphic for a children’s book.

One of my biggest challenges in writing the text was to convey the heart-wrenching tale of the sea turtle’s near-death experience, while making the story palatable and gentle enough for young readers. 

But if this was my challenge, imagine what the illustrator was up against! 

Marta Álvarez Miguéns

“The true story on which this book is based is quite harsh,” said Marta Álvarez Miguéns, the artist behind the book’s brilliant images. “When I saw the video about the rescue, I had a hard time watching it. I am quite sensitive to animal suffering and I don't like to see animals suffering at all,” Marta said. “I don't need to see a very difficult situation to empathize with them.”

From the moment I saw the preliminary sketches for this book, I was astounded at how Marta was able to portray the turtle as believable, yet child-friendly and relatable. 

When I asked Marta how she managed to achieve this, she told me: “One of my biggest motivations in illustrating this story was to get readers to empathize with the turtle as much as possible.” Creating a turtle who was “a bit less realistic,” with a focus on “adorable” eyes from a close-up perspective, Marta told me she “tried to find a balance between sadness and hope.”

It’s a balance she struck more perfectly than I could have imagined.

Here’s an example of just how meticulously Marta’s process reflects her desire to tread thoughtfully, experiment, and refine an illustration when needed. This is an early sketch of a scene where the turtle is trapped in a trawler net:

“I had drawn one of the illustrations in which the turtle was trapped in a net in the foreground,” Marta told me, referring to the top illustration. 

“In the end, I thought it was too much suffering and I preferred to make a general shot in which we could see the sad situation the turtle was in, but without so much sensationalism.”

So Marta replaced the scene on top with the one you see below it. The bottom illustration is the one that made it into the finished book. 

Here it is in full color:

There’s something else about this scene that adds more emotional impact than words ever could. As you can see, Marta created “an emotional link between the fish that accompanied the turtle on its journey” and the turtle trapped in the net. 

Just look at their faces! Nowhere in the text do I say anything about the fish. And yet Marta masterfully created a scene where “we see that some are trapped in the net and others are left outside looking helplessly at the situation in which they cannot do anything. I liked this illustration better because it had many more things to tell than the one with the turtle in the foreground,” she said.

In addition to capturing the emotion involved in the turtle’s harrowing journey, the book also features breathtaking underwater scenes. Marta told me she “wanted to show the beauty and richness of the environment that we should preserve.”

Thanks to Marta’s generosity, this incredible depiction of a Costa Rican coral reef from the book is available as a limited-edition, 5x7 print for anyone who orders the book through my local indie, Print: A Bookstore

I’m so grateful to Marta for these prints, for her glorious art, and for her compassion in striking that sensitive balance between sadness and hope.
