I enjoyed the multiple voice actors in this recording. It really brought the letters to life for me and gave each perspective very interesting characterization. I do wish I had a physical copy to see if there are illustrations. The descriptions were good, but I am interested to see the drawings. 

I love the archival friendship S and V found as they searched for their lost siblings. I thought the way the mystery was unraveled and revealed was very interesting. 

I absolutely cackled at the brother’s letter at the end. Was honestly what bumped this up to a 4 for me because the absolute comedy of him coming to the same realization as everyone else in the book at the very last moment had me laughing out lout at work while listening to this audio book. This book does end sort of up in the air, but I like to imagine they found what they were looking for.
