“My God, this book is delicious. The Engagement Party is a swallow-down-in-one-desperate-gulp kind of thriller, so compelling I felt feral turning its pages. Darby Kane is a master at constructing juicy, twist-filled plots. The multiple points-of-view, ensemble cast, dark, isolated Maine setting, and decade-old secrets combine to create a locked-room mystery of the highest order, a puzzle-box so clever and sly it would make Agatha Christie proud.”
