If you're a fan of the original series, you will most likely really enjoy this. This is a stellar page-turner with a lot of action and happenings. Like the previous three books, I never much enjoyed the first part but the second and third parts of this book are a lot of fun. I'm a huge fan so I made sure to begin reading at midnight when it was released and then finished it this late morning.
I don't want to spoil anything but overall what I liked about this prequel are all of the interconnected pieces from Tigris to the Mockingjay and the history we read about in terms of the formation of the games. The only aspects of this book I did not like were some of the choices in terms of the plotting.
DREAM CAST: Snow - Finn Wolfhard Lucy Gray Baird - Sophia Lillis Dr. Gaul - Tilda Swinton (This is the casting that matters the most IMO) The Grandmom - Meryl Streep Sejanus Plinth - Tom Holland Tigris - Zendaya
The rest of the cast I'd imagine could be dependent on an open casting call which would be really cool.
