This is a DNF for me at 23%. Thanks to the publisher for a copy in exchange for an honest review. 

I wanted way more rum runner and code breaking activity as promised, but at this point all we've really gotten is a very little bit of both with a lot of 'baby on board' and 'I grew up in poverty'.

Also for being set in Miami and Key West, it doesn't really feel like it's been set there. The author just calls out a well known street and the Key West roosters, but doesn't bring Key West to life.
