I confess I have not heard of Colson Whitehead or Lois Lowry, and I have not read anything by Charles Yu or Patricia Wrede; does anyone have any particular thoughts on those writers? The others on the list which I have not read are all works I plan to get around to, or at least sample, by authors with whom I am familiar.
