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

Book 3 in the young chapter-book series--perfect for fans of Princess in Black and Mercy Watson--about 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 utterly charming chapter-book series.
