Barbara Metzger loves to play with words, making jokes and twists with almost every sentence. It's fun to read her books, which are mostly historical romances playing in the Regency. But the setting in Jack of Clubs is so fragile that it's hard to keep the gossamer plot alive. Even the characters don't seem to believe in their world, so their problems aren't big enough even to giggle at.
It's a fun book at the sentence level, but doesn't work at any scale bigger than that. C-
