The concept of Underground Airlines sounded intriguing; unfortunately, the execution didn't do it for me. Not only did the plot drag, but also I felt a lack of connection with the main character. It fell flat not long after the beginning and I was more interested in getting through the book than wondering what would happen next (but hell if I didn't keep at it because I am a WRITER who reads WIDELY: the reason I stick often with books that aren't my thing). I just wasn't excited to keep picking this one up. I'm in the minority though--it's rated almost 4 stars overall here on Goodreads.
