Grown up Kate, now in her 20s tells most of the story.
It is a narrative full of love, sacrifice, loyalty, persistence, projection, and descriptions of attachment styles that are fascinating.
Kate certainly has become avoidant although she had been every attached to her brother, Matt the youngest son. This attachment dynamic is the plat of the book. While Luke the oldest, and Bo the youngest are interesting characters, the primary creative tension revolves around Matt and Katie, 16 and 7 when tragedy strikes the family.
This novel is an extraordinary description of sibling relationships and the significant role they play in our growth and development.
I give Crow Lake a 4/5 and recommend it if you are interested in family dynamics especially those between siblings who are thrown upon their own resources to care for one another.
I would recommend this book to students entering the helping professions especially for its depiction of attachment styles.
