Ruth Ware has done it again!!!! 

Thank you to Netgalley and Simon and Schuster for an ARC of this exciting book. 

This story was gripping the entire time. Jack was a really great leading lady with a ton of really cool skills and knowledge. I thought the pen tests were fascinating, the hacker bits were amazing and her journey was amazing. 

Loved reading this book, can't wait to listen on audio to try to pick up extra clues along the way!!!!
