An awesome read!
Format: Kindle
Totally worth the read and then all the twists! Wow! Think thriller, mystery, and you get an airplane seat number. Huh? That’s what I wondered, and then I read this awesome story that blew my thoughts apart. I loved how Drew brought us on her journey to discover what happened. I was blown away at this seemingly complex telling that I was hooked and flipping as fast as I possibly could to see if Drew would find Kate. What Drew found was previously unknown information that kept guiding her to more clues. I was fascinated as each clue led us to the ultimate confrontation leading to an awesome conclusion. What a journey I was taken on and thoroughly enjoyed!

Started this book Saturday and finished on Sunday! I could not put it down! It was sooooo fun trying to figure out what would happen next- i was glued to the book and couldn’t wait until the mystery was solved! This was one of those books that I wish I could read for the first time again. I LOVE Rita’s books, i can’t wait until the next one & I’m keeping my fingers crossed for another thriller from Rita!

Really good read

This is a very good read. I started reading and didn't want to stop. Kept my interest from page one to the very end. Characters are interesting and likable. Suspense, mystery and a sweet romance. Thanks for a great book.

Okay
Format: Kindle
The story was not too bad. It was a fairly quick read, and it kept my attention. I started to rush through the end of the book because I did start to get a bit bored of the clinginess of the main character.
