Bestselling author of the Ranger in Time series Kate Messner continues with the third book in this fun, science-based series about a family dedicated to rescuing animals.

It's summertime and Ana and Sofia are visiting their cousins Ivy and Ezra in Florida! Ana loves being back in her hometown, going to the beach and eating ice cream again. Ever since her family moved to California, Ana's been thinking about trying new things . . . like signing up for the Makers Club instead of playing volleyball again with Sofia.

Then the cousins get a call about an injured gopher tortoise that's been hit by a car. Ana and Sofia join Ivy and Ezra--as volunteer critter couriers--to transport the animal to the local wildlife hospital. And since the city hasn't done anything to make crossings safer for the endangered animals, the four kids come up with a plan to do just that. Ana has never been one for the spotlight but the tortoises need her!

If Ana can gather the courage to stand up for the tortoises, can she be brave enough to tell Sofia that she wants to try something new?
