I have several books for sale on the Kindle site, so I know how important reviews are for indie authors.  I am happy leave on for this charming book. Any work composed entirely of letters doesn't sound like it would pull you in (84 Charing Cross Road is one exception), but this one does.  In short order you get to know Jack Olsen and his family, plus many characters of an alien race.  I found myself reading to a stopping place and needing to leave (I'm on vacation now), but making excuses to rip through another letter or three.
