Rounding up from 3.5 stars. 
 Seven Days of Us is an entertaining, quick read about a family forced into isolation together -- a perfect setting for secrets to emerge and for walls to come down. Phoebe and Olivia rediscover the sisterly affection that's been absent since childhood; Andrew and Olivia finally come to understand one another's obsessions and sacrifices; Emma and Andrew confront the iciness that's taken hold in their marriage. Meanwhile, Phoebe's fiance crashes the quarantine, as does an American who ends up being the long-lost illegitimate son Andrew never knew he had. 
 The story moves along at a smart pace, with each character getting bits and pieces of the story. The main chapters focus on the seven days of quarantine, while within each day, there are sections devoted to the different characters, each section showing the time and the location within the house -- which lends the narrative a claustrophobic air that's appropriate for the involuntary intimacy and close quarters experienced by the family. 
 I do wish the author had included some sort of introduction explaining the quarantine rules. Why would a doctor treating epidemic patients be allowed back into England, passing through a major aiport, in order to go into quarantine with her family? Is this a normal protocol? Sure, readers could Google it, but it would have been helpful to have a bit of context, considering that this is the major plot driver of the entire book. 
 My interest never flagged, but certain plot developments (no spoilers here!) were completely obvious, and a tragic turn toward the end of the book seemed both jarring and unnecessary. 
 Overall, I recommend Seven Days of Us. It's a pleasant, amusing story of family dynamics, and the ups and downs of the relationships between parents and children, between siblings, and between spouses definitely ring true.
