I've read over 100 casual books and this one was tailored made for me. Everything was perfect about it. I read a book about US Navy on Memorial Day. The Navy personnel were not morons, but solid people seeing the responsibilities they had. A Genius of Geniuses most-likely for the lead female character. What I know of both of these type of people the author portrays correctly. The first 70% of the book I refused to not put the book down. The interaction between a Genius and A Naval Submariner that in a sense she was throwing his way of doing things into new waters was awesome. Totally acceptable interactions. I thought at the beginning that the child-like mentality was week but as the book went on it was the right decision. The Last 30% was mostly just about them getting together and it was like a let down only because the new stuff that was going on till that point was so riveting.
I read as a library loan, it was so good I bought the audio version.
