Dark Water Rising, by Marian Hale, was published in 2006 by Henry Holt.
You’d think every person from Lampasa to Houston wanted to go to Galveston this hot August day. Everyone but Seth. Galveston, Texas, may be the booming city of the brand-new twentieth century, filled with opportunities for all, but to Seth it is the end of a dream. He longs to be a carpenter like his father, yet Pap has moved the family to Galveston so that Seth can become a doctor. Still, the last few weeks of summer might not be so bad. Seth has landed his first real job as a builder, and there’s that girl across the street, the one with the sun-bright hair. Things seem to be looking up…until a storm warning is raised one sweltering afternoon. They say a north wind always brings change, but one could ever have imagined this. Set during the Galveston Storm of 1900, this is an unforgettable story of survival in the face of natural disaster.
