The Dalton Affair will be a single book, and it will cover the entire original trilogy
Chapter 3 of TDA ends at around the same point as Chapter 6 of the first book of TNA, while Chapter 4 features the company picnic (which happened in Book 1, Chapter 10 of TNA), and the preview for Chapter 5 mentions the gala (which happened in Book 1, Chapter 12 of TNA). This likely means that each chapter of TDA will cover (or gloss over) several chapters of TNA's story from Sam's perspective, ending at the same point Book 3, Chapter 20 of TNA ended.- Jossed. PB have confirmed that Chapter 9 (which will cover the events of the original series' Book 1 finale) is the series finale, meaning that TDA only covers the events of Book 1.
