A layered, beautiful story of a lifelong friendship. An appropriate conclusion to a lifelong friendship that we follow through 4 books. In this we follow them into old age, between 1970s to the early 2000s. Filled with love, loss and strife. Ferrante has a compelling ability to infuse innumerable emotions into her writing, to bring out the beautiful but more importantly, the devastating and ugly parts of being alive. A brilliant series.
