The Aldens are spending spring break on a beach, but they aren't just soaking up the sun. They're protecting an endangered species! Their job is to mark sea turtle nests so the eggs can be moved to a safe place to hatch, but someone is digging up the eggs without permission. Can the Boxcar Children figure out what's going on and help save the sea turtles? Adapted from Gertrude Chandler Warner's story of the same name, this early reader allows children to start reading by themselves with a Boxcar Children classic.
