Ahoy there me mateys!  This book takes place on a generation ship, the Calypso.  After a failed attempt to colonize a new world, the survivors feel that they had no choice but to try to make it back to Earth.  However, several generations later, the ship is badly damaged and the likelihood of survival is looking dim.  Jacklyn "Jack" Albright, the first mate, is struggling to keep the ship going and looking for any solution.  It all gets worse when something inside the ship starts killing.

The positives of this book began with Jack.  I appreciated her tenacity and stubbornness.  I really was rooting for her the entire time.  I also grew to like the android, Watson.  Watching these two characters interact was compelling because of how their relationship changed.  I also enjoyed the concept of failed colony trying to make it back home.  This is a topic I wish was explored more in sci-fi.

While this book was a quick read and enjoyable in some ways, there were also some major flaws.  The big reveal dealing with the MIA captain was unrealistic, campy, and tropey.  The cause of the "engagements" damaging the ship is never explained and used as a deus ex machina for the ending.  I thought the threats inside the ship were fun, if unoriginal.  It seemed silly that the whole fleet could be taken out by them and also that Jack took forever to figure out what the banging was.  There was attempted horror in having a theme of opening doors that also ultimately didn't make much sense to me.  Also life onboard the ship isn't explored much and there are no real secondary characters other than to provide fodder for plot points that go nowhere. 

This book did not keep me in suspense but that could have been due to the short length.  A longer novel much have fixed some of the issues.  That said, I like the writing style enough to read something else by the author.  Arrrr!
