The Helsinki Affair is another spy thriller by Anna Pitoniak that does not disappoint. So many twists and turns and moments that will leave you shocked by how it all goes down. 
 
 CIA Agent Amanda Cole must find out who killed a Senator and why they did it. What she wasn't expecting to find along the way though is the connection to her own father who worked undercover during the Cold War. Amanda finds out information about her family that she didn't know about, and the danger it puts her in as a CIA agent. Full of twists and turns along the way as she unravels the truth of her own parents' past and the case she is working along the way she discovers things about herself with a little help from a senior agent (Kath) who is there to guide her along this investigation. 
 
 Overall this book is high stakes from start to finish with how many people and countries are involved in it. Amanda has to walk a very fine line as she is uncovering all these secrets, and it's one that does start to get to her after a while. She must make hard choices not only for the case but in her personal life as well. While this book is a long one and at times can feel a bit like non-fiction with all the information that is told about the Cold War it's also one that is very well researched and you can tell the author truly cared about the subject. I enjoyed Amanda and Kath's characters and all that we learned about them and their careers in the CIA. 
 
 I think this book is great for anyone who loves spy thrillers and wants more of them. If you liked Pitoniak's first book you'll love this one. 
 
 Can we get a spin-off of Kath's life because her life and the work she has done over the years sounds fascinating!
