Carrie's Run is a prequel to season one of Homeland. In 2006, CIA agent Carrie Matheson is in Beirut on a mission to make eyes on a contact known as Nightingale. However, it's an ambush that Carrie barely escapes. She soon discovers that there is a bit of consipracy that goes to one of the highest echelons of her government to create a civil war in the Middle East. 
 Andrew Kaplan writes a decent spy story but it wasn't Homeland. For one thing, Carrie isn't that competent. In this novel, she's sort of a rain man savant super spy. It was not believable. Carrie's voice wasn't authentic. It could have been anyone. 
 There was a lot of sex in this book. It came out of nowhere. It happened at a lot of impromptu times usually during an op. I hated how they did the Carrie-Estes "affair." On the show, Estes had a lot of hate for Carrie for ending his marriage. In Carrie's Run, he was understanding and admitted that his marriage was already over. 
 Carrie's Run felt like an alternate universe Homeland. I'm pretty sure Carrie did not do any of this. Not the Carrie I've seen the past three seasons. The plus side is that it is a very quick read and I am kind of glad I didn't buy it.
