Griselda Takes Flight ($9.49 US), by Joyce Magnin, is free for UK Kindle customers (
UK link). This one is from Christian publisher Abingdon Press, so I'd expect it to be free in the US within a day.
Book Description
Now that her morbidly obese sister, Agnes Sparrow, is comfortably dieting at the Greenbrier Nursing Home, Griselda learns to fly—literally—after a pilot makes an emergency landing and creates quite a ruckus in the otherwise sleepy town of Bright’s Pond.
But Griselda’s newfound freedom—and her flight time with handsome pilot, Cliff—is hampered by other happenings in town. Like the gold digger who prances around town and is supposedly engaged to Stella Kincaid’s brother—the lottery winner who is in a coma. And there’s Ivy Slocum’s dog, Al Capone, whose adventures continue long after they should.
When Chief of Police Mildred Blessing starts investigating the gold digger, however, things really heat up—for Griselda and all the residents of the unique Pennsylvania hamlet called Bright’s Pond!
