The Lucky Day (Seashell Key #3): A Chapter Book

The Lucky Day is the third book from author Lourdes Heuer and award-winning illustrator Lynnor Bontigao’s young chapter-book series—perfect for fans of Princess in Black and Mercy Watson—about the adventures of a diverse community of kids living in a beautiful seaside town

It’s the last day of school before spring break, but there’s still so much to do! Mateo is on a mission to catch a leprechaun, and Sasha and Sophia can’t wait to work on their school garden. Elena just wants to read about dinosaurs, but when she finds a secret map in her textbook, she’ll need all her friends to help her find the treasure of Seashell Key—and make a treasure map of their own!

Filled with a vibrant cast and lots of spring fun, this is a great addition to an exciting new chapter book series.
