Absolutely flew through this one! Has all the makings of a thriller that I love to read and it didn't disappoint me at all!. I was hooked from the start, and following the events from that event that happened in the opener of the book was always gripping and kept me guessing. I loved the different sections of the book and how the tension really grew as it went on! Because of the setting the claustrophobic sense is so high and I really enjoyed that a lot. I thought the characters were all great , and each had their own strong voice here and played crucial roles. This is my first book by this author but I can't wait to read more! Would highly recommend to any thriller fans 100%! So twisty and such an exciting read.
