These say audio books but I actually read the entire thing in two volumes, handed down from my grandmother's library through mom, who passed away last year. "Sweeping saga," a term used so often in describing movies, or maybe Michener books, certainly applies to this. The central premise is the sale of a tontine, sort of a lottery, in which you buy shares and wait 30 years for them to mature and start paying an annuity. It begins in the early 1800s so many of those buying shares died or disappeared to parts unknown during the 30 years, increasing the amount available to be paid out to the survivors. Being last man standing ensures great monetary reward but as you approach that position, could put your life in danger! In following the tontine share owners, the novel lays out the many technological and social changes that occurred during the century or so of its scope, throughout the British Empire, so if you like historical fiction there is plenty in here to engage you. The characters are all quite distinctive and thoroughly drawn, although types seem to repeat themselves over generations. I really appreciate the detail in describing clothing, home furnishings, and architecture, rather than just the political events, pursuit of the vote for women and child labor laws, international trade, advent of railroads, telegraph, and telephone.
