This is book number 3 in the Faithgirlz / Soul Surfer series.
It took real faith and courage to get Bethany back on a surfboard after losing her arm to a shark. The Soul Surfer fiction series is based on the life of surfer star Bethany Hamilton, as she and her friends discover God's love and guidance as they tackle the waves life hands them. In book three, Storm, a car wash and a surf-a-thon with inflatable toys seem like great fundraisers for a mission trip for Bethany's youth group. But an unexpected and life-threatening challenge for Bethany and her friend Holly brings a mysterious twist to their plans for Mexico.
