Lea is ten years old and ready to explore the whole world, just like her grandmother! But first she'll start with a family trip to Brazil, where her big brother is studying the rainforest. Lea is really excited to see the ocean - and when she does, she realizes she'd rather take a picture of it than swim in it. Can she overcome her fear and dive in? Then she meets a fun new friend who inspires her to embrace the thrills and beauty of Brazil. But when the fun turns to danger, she must find the courage to face adventure head on! Where will the next adventure take her?

Lea is all set for an animal-discovery adventure! She's never been to a rainforest before, and her mind is filled with exciting thoughts about the animals she'll get to see - and the pictures she'll get to take deep in the jungle. During a hike with her brother through the Amazon rainforest, they discover a baby sloth that is badly injured. Lea quickly decides she must do all she can to help the little sloth survive. But as she learns more, she wonders: "Is that the right thing to do?"

For spring break, Lea has invited her friend Camila to St. Louis for a stateside adventure. They find a stray kitten and make a mysterious discovery while visiting a grand but crumbling mansion. Lea is determined to uncover the secrets of her discovery, but in her search for clues she forgets to be a good host to Camila. And when Lea's best friend, Abby, becomes fast friends with Camila, Lea feels a little left out. Can she find a way to reconnect with her friends—and solve the mystery, too?
