Zugzwang — Rebecca A. Engel

Valerie Urniak Cardonza never thought of herself as someone with a nemesis, but now she has two: one who is a threat to her marriage, and another who is a threat to her family.

It is Valerie, not her chess-savant son Bobby, who finds herself in a zugzwang, a chess term that means any move will only make things worse. In Valerie's case, whatever she does may turn out deadly â€" but for her, or for Bobby?
