This is the second novel in a row I've read (after Enchanted Islands) that's written as a sort of memoir from the perspective of an older person looking back. I'm not overly fond of traditional memoirs and wonder if this may in part account for my less than enthusiastic reaction upon finishing.
What this book does have going for it is a charming, somewhat unreliable narrator. Her asides and style as a storyteller often delighted and amused me. Mary is a naive girl at the start, and as an adult seems not much wiser. As a reader you may arch your brow at the gaps in her knowledge or what lies beneath her personality quirks (e.g. as a woman in her 50s at the end, she has developed a kind of fetish for reverends, owing to her first love, explored throughout the book). Mary is so plucky (and often critical of others) that I assumed she was still a child when the story began (in fact, she's a young lady already).
Returning to what I'm describing as memoir-ish--and an author's note explains that Mary's father was a real person, if not the whole family--there's only so much narrative thrust to the story. The plot advances in short chapters interspersed with others that give some background to the characters and to whaling. Essentially, Mary relays an account of a particular whaling season in Australia, most significant for her because she meets her first (and only romantic) love.
The novel was pleasant enough to read, but I needed something more and was also left confused by the end. Why end on that moment?
