Through Waters Deep by Sarah Sundin
 A great historical fiction that takes place at the start of the American entry to World War 2.  This is a story of intrigue with a bit of romance.  Mary and Jim must work together to figure out who is committing sabotage on the USS Atwood.  I liked how the book kept you guessing as to what was going on and who all was involved.  The characters are engaging and I liked seeing how they evolved to become the people they are to get the job done.  I received this book free from the publisher to review.
