Grandma and Wren don't understand why Grandpa is building a new farm house when the one they have is perfectly fine. But on November 2, 1927, everything changes. Nine inches of rain fall in Vermont in two days. The river keeps rising. One by one, the townspeople and their animals move into the unfinished house because it is the only one left on high ground. But Grandpa is still out in the storm! Wren and Grandma head out in a boat to look for him: will they find him? An author's note describes the historical setting of the story: the Vermont Flood of 1927.
