Anne Tyler's new novel A Spool of Blue Thread is just out here and in the US, and the respective covers are above. Which do you prefer, or which one - if you knew nothing about the author - would draw you to pick up the book? My vote is firmly for the American design, that is the one on the right. I would also respond favourably to this summary, again from the US:
"Brimming with all the insight, humor, and generosity of spirit that are the hallmarks of Anne Tyler’s work, A Spool of Blue Thread tells a poignant yet unsentimental story in praise of family in all its emotional complexity. It is a novel to cherish."
