What is the setting of The Shell Seekers by Rosamunde Pilcher?

The novel occurs in a variety of locations, but each is important to Penelope. The novel starts in Podmore's Thatch, but although this is Penelope's most recent house and current sanctuary, there are a number of other environments where important actions take place. Podmore's Thatch is the representation of Penelope's children interfering with their mother's wishes and allowing them to dictate how she is going to live. Carn Cottage in Porthkerris, on the other hand, is where Penelope's heart still resides and where she makes her final trek before passing away. It is here that many of her past recollections occur.
