There's a lot of talk about deep point of view right now, and, as far as Fiorella can see, nobody does it better than Susan Elizabeth Phillips, which is why Fio keeps a copy of Heaven, Texas by her side while she writes. If Fio's chapters seem to be bogging down, she delves into Heaven for a page or two and gets herself into gear again.
Fio's read prescriptions for writing deep POV, which is basically getting so far into the character's viewpoint that one is practically writing first person, but there's no substitute for feeling how to do it so that it flows naturally.
The oil's boiling. Dive in.
