** spoiler alert ** 
 This was a book that I really raced through. Lots of interesting twists, and you really wondered what the heck the husband had been up to. Any book that gets me that into it is worth it, but then at the end, the whole Corbin is a bad man twist made me really uncomfortable. The author never mentioned the race of any other character, but made such a big deal about Corbin and how black he was. Then he turns out to be crazy and going to rape Iris for fun?? It just seemed unnecessary and gross. Then he was shot while unarmed, but it goes into how he was so big he could have killed her easily. Just in poor taste for all the issues that happen today with shooting unarmed black men. I will give the author the benefit of the doubt, but why mention race at all? The only black character turning out to be a crazy rapist was in poor taste. 
 Then the husband reappears, and his explanation for what happened really doesn't make sense. What would he have done if his plane didn't crash? He was counting on that in order for him to remember him in a positive light. It just suddenly got really fuzzy. Are we seriously to believe that Corbin forced this guy to be so bad? 
 Luckily the end was pretty much redeemed because I audibly gasped when Iris hit that panic button. Didn't see that coming.
