“The Martins Return” picks up where the first book (“The Martins”) left off and tells the story of where the Martins go when the weather gets colder in North America. Freddie proudly explains to his little sister, Loretta, how the Martins migrate to South America and then return again to grow their family when the weather gets warmer. This educational and entertaining family adventure story is for children of ages 3 to 8 years. Younger children can also enjoy the fun story and colorful pictures, while parents read to them.
