Post-apocalyptic novels are not my choice of reads, but this one held promise because it was not an end-of-the-world scenario brought about by warfare or alien invasion (a seemingly common element among novels of this genre). The end (of civilization) came suddenly, but also unfolded in a natural enough timing and setting to be plausible. I liked how the threads of past and future, of the different characters' lives, wove to tell the story. I am giving it 3½-stars because I felt that the emotional tapestry of the characters could be told with greater detail, and thus, garnered more reader empathy. Instead, I felt that that aspect was a little bland, with not much contrast against the stark landscape.
