This one definitely needs a re-read to really get into its depths, but on a first read, it was easy to delve into and mesmerising. I already loved the Seasonal Quartet, and this - while it has no connection to the quartet in terms of characters - picked up right in the same manner. I love the way Smith's narratives fit into current events, the allusions to things we've all lived through, and yet, the way these novels make the reader view these events with a fresh eye.
This book keeps much of the mystery of its plot to itself, and feels more open-ended - almost like a short story in the brief glimpse we get of the characters' lives. In this way, Smith's novels always make me think.

Beautiful book, highly recommended if you liked the Seasonal Quartet. If you haven't read those, I'd actually recommend starting with Autumn.
