52 in 52 - book 23 - 6 Sacred Stones - Matthew Reilly
Absolutely aching for the 4th book in this series, due out next month, so in preparation I've embarked on reading the series again. I've had issues with finding time to blog, paired with IOS10 blogger issues, I finished this book on September 17th :)
As always, Matthew Reilly is an amazing writer who keeps you on the edge of your seat! I can't recommend this series enough!
