Alexandra by O’Dell, Scott (1983)

Vintage Ex-Library Hardcover in Good (G) condition. Clean and straight with standard library markings. First Edition. 

For many generations, the men in Alexandra’s family have been sponge divers — first on the Greek island of Kalymnos and now in the Florida village of Tarpon Springs. Diving has always been considered a man’s job by Alexandra’s family — dangerous and demanding. But when tragedy strikes, Alexandra decides to become a sponge diver herself despite her family’s objections. And she learns that as dangerous as the underwater world can be, there are always more dangers waiting on shore . . .
