The process



They say that when Puerto Ricans move to the island they have trouble falling asleep without the lullaby of el coquí. It happened to me. I sorely missed this adorable tree frog’s song. One day, thinking about my island, I started sketching coquíes from memory. And from my sketches Rafi and Rosi were born. 

From the very beginning I knew the stories would be about the relationship between an older brother and his little sister. The stories mirror my husband's antics growing up in Puerto Rico and his relationship to his younger sister. The character of Rosi has a little of me in her. 

The siblings’ adventures are set in Puerto Rico and share the island's stunning natural beauty, rich culture, centuries-old traditions and history. The island has always been a source of inspiration for my work and I'm proud that Rafi and Rosi can tell a little of its story with beginner readers. More extensive background here.


To create the art I used a sepia watercolor pencil for the outlines of my characters. Then I filled the shapes with Windsor and Newton watercolors. The sepia outline bled a little as I painted the tree frogs giving my characters warmth.





45 min. A slide show in DVD format telling how the characters were born and the stories developed, a demonstration of the "magic fingers" trick. Recommended for grades 1-2.


45 min. A reading of Queen for a Day, a slide show in DVD format that explains the process in the making of a book, and a peek at an authentic vejigante costume.

The making of a Book, Rafi and Rosi: Music!

"Delacre affectionately depicts the brief conflicts and abiding love between this busy duo, adding appealing watercolor illustrations. While Rafi is older and savvier, the verve with which Rosi approaches the panoply of childish emotions will jibe with kids fresh from such mastery themselves." – Kirkus Reviews

"These frog siblings are mischievous, but it is clear that they love and appreciate one another. Their emotions and experiences are universal to childhood. The charming cartoon illustrations are integral to the amusing text." – School Library Journal

"Puerto Rican tree frogs Rafi and Rosi team up for some informative hijinks in this beginning reader.... Delacre illustrates this title in sunny beach shades of sand and sky, making the most of the expressively big-eyed tree frogs and their spindly but graceful limbs. Rafi and Rosi are a likable pair of siblings, and their science-oriented activities, while not intrusive, provide an underlying solidity to their interaction." – Bulletin for the Center of Children's Books

"Rafi the irrepressible tree frog is back with his younger, plucky sister, Rosi…. A sweet and engaging story." – Kirkus Reviews

"...a good addition for libraries wishing to add diversity to the collection, or those serving Spanish-speaking children." – Booklist

"...their shared joy for music and dance ultimately shines through any upsets—a valuable reflection of unity.”– Kirkus Reviews

“Lively illustrations done in watercolor and colored pencil adorn the page…. Ideal for early fluent readers.”– School Library Journal
