Glad I persevered but sorry to use such a word where reading is concerned.
My FIL was a Baptist minister and I've good memories of comet Hale-Bopp (I was pregnant), so there's that.
I did enjoy it in the end but it's a qualified pick: the vibe was more 1897 than 1997, which was disorienting, and several minor characters, along with the whole Maria Vaduva story arc, didn't quite come into focus.
I did like Grace and Thomas's complex friendship.
