Once again, Ruby the giraffe is turning her summer into an adventure she will never forget. This summer, Ruby wanted to spend her time helping others, and with the advice of her aunt Kelly, she travels to Oahu, Hawaii, to help green sea turtles. The green sea turtles are on the "endangered" species list because their population is quickly decreasing. But why? Ruby travels all over Oahu to find a green sea turtle to talk to in order to find out how she can help. Ruby's Hawaiian Adventure is a fun and entertaining story that teaches kids about conservation efforts that can save green sea turtles while exploring many famous landmarks in Oahu.
