The novel is about family and parenthood. Both are important. Both are complicated and messy. Both are needed to get through life. Not everyone is fortunate to have a good family. Family bonds are strong. Time has a way of cementing the bonds.
There are different dynamics portrayed within the family. I loved the bond of sisters.
Secrets are corrosive. Sooner or later they leak out. They are a burden that needs to be released. “Shedding secrets had lightened the load.” Secrets can become barriers between people. “Secrets are like walls. They stop you getting close.”
