This is the story of Rose and Page Tico and the mission undertaken by the young sisters immediately before the beginning of the movie, The Last Jedi.
Page is the woman at the beginning of the film who struggles to release the bombs from her incredibly slow-moving bomber. Rose appears throughout the rest of the film and later saves Finn.
It is a moving tale, well-thought out, and it expands on the theme of sacrifice for the greater good, but also gives us more insight into Rose's motivations during the movie.
Wein also wrote Code Name Verity. I was hoping for a similar, dual-POV tale, but as told from Rose's perspective it is still gripping -- in part because we know what happens, ultimately.
We cried at the end.
