The High House by Jessie Greengrass (Signed)
Paperback - bookplated
Perched on a hill above a village by the sea, the high house has a mill, a vegetable garden and a barn full of supplies. Caro and her younger half-brother, Pauly, arrive there one day to find it cared for by Grandy and his granddaughter, Sally. Not quite a family, they learn to live together, and care for one another.
But there are limits even to what the ailing Grandy knows about how to survive, and, if the storm comes, it might not be enough.
