First introduced in Rafi and Rosi (HarperCollins, 2004), Lulu Delacre’s tree-frog siblings return to celebrate their native Puerto Rico’s Carnival in a charming follow-up offering. Rafi and Rosi’s relationship embodies familiar ups and downs of sibling encounters. Rafi is often trying to get the best of his little sister, but his put-offs, tricks, and teasing always result in a guilty conscience. He loves Rosi, after all, and he wants to make things right again. As for Rosi: she may be little, but as Rafi will discover, she’s not too small to play a trick on her big brother. This volume designed for newly independent readers is comprised of three stories, each one highlighting a different aspect of the festive Carnival celebration. Occasional simple Spanish words, defined in a glossary, are woven into the text, which features large typeface and short lines set against Delacre’s own illustrations. (Ages 4–7)

Two Latin American tree frogs, mischievous Rafi and his younger sister Rosi, enjoy the events of Puerto Rico's Carnival season.
