I highly recommend the audiobook of this, if you like audiobooks. All of the narrators were excellent, and having a variety of narrators does help a lot with an epistolary novel to help you keep track of who wrote the letter you're reading. If you enjoyed this, I would also recommend the audiobook of The Guernsey Literary and Potato Peel Pie Society, which is another story told via an exchange of letters, but just after WWII. I did cry while listening to this and wrapping Christmas gifts

after the death of Will, when his letter to Evie is read

, so be aware this is a more somber Christmas read. Many of the tragedies and horrors of WWI are touched on. If you watched Downton Abbey season 2 (or similar media about that period) you will already be aware of some of them. Despite the surrounding darkness, the characters try so hard to keep seeking beauty and connection in their lives. The romance is slowly unfolded across many letters, but the friendships are always clear and strong.
