Join Max and Sofia, two kids trying to save the environment one problem at a time with their magical sailboat. Their latest mission? Cleaning up the plastic waste that's hurting puffins and belugas in Iceland.

In Starry Bay, summer vacation means snorkeling for sea glass by the beach, until Max and Sofia come across an abandoned sailboat. With a spin of the wheel, Wind Rider transports them to animals who need their help! This time, they drop anchor in Iceland's frigid waters, where Max and Sofia team up with the Puffin Patrol, a group of Icelandic kids who protect and preserve the local puffin colony. But it seems that the puffins aren't the only ones in trouble. Max and Sofia will have to think fast to save a beached beluga whale.

Wind Riders: Whale Song of Puffin Cliff is the fourth installment in this chapter book series. Each story visits a new location and introduces a human-made problem endangering animals and the environment.

With nature’s highest stakes and environmental activism baked into each book, as well as fun scientific facts included at the end, Wind Riders promises to be the chapter book series for newly independent readers who love nature documentaries and are hungry to learn about the world around them.

There is an emphasis on collaborative problem-solving, compassion for the Earth and all its inhabitants, and friendship. Wind Riders is the perfect STEM chapter book series for fans of Magic Tree House, The Magic School Bus, and Zoey and Sassafras.
