Wish

Bee's brother, Tommy, knows everything there is to know about sharks. He also knows that his life will be cut short by cystic fibrosis. And so does Bee.
That's why she wants to make his wish-foundation-sponsored trip to swim with a great white shark an unforgettable memory.
But wishes don't always come true. At least, not as expected. Only when Bee takes Tommy to meet a famous shark attack survivor and hard-core surfer does Tommy have the chance to live one day to the fullest.
And in the sun-kissed ocean off a California beach, Bee discovers that she has a few secret wishes of her own. . . .
