I've been reading and re-reading so much Kurt Vonnegut lately.
Recently completed: Wampeters, Foma and Granfalloons (Opinions), Hocus Pocus, Cat's Cradle, God Bless You, Mr. Rosewater.
Ongoing: Timequake, Galapogos.
Still to go: Bagombo Snuff Box, Breakfast of Champions
My favourite so far is Cat's Cradle, but in my head, they're beginning to blend into one mega book.... Pretty much like how my weeks and months are blending into one mega... er, week and month... and then, maybe years into one mega year.
