I love the idea of imagining what things might have been like for them. We talk about how Nephi and L/L were all brothers, but we rarely think about how their behaviors would have affected the daughters of Ishmael, except when they're mentioned briefly on the ship. Imagining their lives and reactions makes them feel more real and relatable. This story also gives a sense of what a huge sacrifice this may have been for them. No email or phone to keep in touch. Just ... gone. I think
Hmm... I wonder where the rest of my comment went! I also can't remember what it was anymore! Sigh.
For the curious, I bogged an author commentary. http://annalieselemmon.com/published-works/daughters-of-ishmael/daughters-of-ishmael-author-commentary/And I have much to say on your question, but I will refrain for the moment.
