I was hesitant as I started the book - it shuffled along at a halting pace for the first chapter or so as histories and characters were laid out. Once the strong voice of Teller was established, however, the book sailed along cleanly.
The myth of The Pilot, the life of Teller and her adopted son, Samad - all revolving around choices and growth - moved me immensely. Surviving great losses being a central theme to the book - the sort of losses that all involved see no way through and yet years later can look back at with a realization of a passage or a lesson learned.
Amy Thomson handles all of this with extreme care - the tender relationship that grows fiercely personal between Teller and Samad, Teller's long-time lover, Florio, the people that both Samad and Teller interact with.
I agree with another reviewer, however, that Thomson really dumps the emotional growth side of Samad's sexuality right into the gutter. Samad's homosexuality is a casual jibe between he and Teller, a thing that happens after dark at shipyards and parks and fast - a thing that fades in the day.
Some part of that might be a growth process for Samad - wild, reckless and unwilling to form long-term relationships with others outside of his 'family' and perhaps at the close of the book the mature Samad who begins to find his own voice and way in the world of Thalassa & harsels will be the Samad who also develops lasting relationships with other men - perhaps.
But this is just a tic of the book - and should not distract from the central message and themes. This book was cathartic for me and had me a bit emotional (happy & sad) as the book drew the its end and sailed away into the sunset.
