I received this free from NetGalley and the publisher for an honest review.
To start you absolutely have to read the first book in the series titled Extracted. If you don't you will be lost. Now on to the good stuff. I loved this book even more than I loved the first. There is non-stop action. You care for the characters so much that you worry about them. The dialogue is great. Actions scenes are awesome. I will warn you though that the time travel aspects will twist your brain into a pretzel, but it is a fun, interesting, suspenseful read and I can't wait for the next one.

This series needs more than three books.   The characters fit together perfectly each one filling a vital role like The Beatles.     This is THE TOP TRAVEL BOOK SERIES EVER WRITTEN.   a perfectly well balanced perfectly seasoned book.    This time travel book is to the genre of what Jane Eyre is to the romance genre.

Fantastic sequel to Extracted. 
The main characters are well rounded and easy to like in the main, I was certainly quick to get behind and root for them. The antagonists are also described enough so that you can understand them, even if they are distinctly disagreeable.
The story is complex, engrossing with many twists to keep the reader's mind hopping. The use of time travel opens up many scenarios that otherwise wouldn't be possible.
In all this is an exciting book that I would willingly recommend.

Continuity o f story, thickening of plot and seemingly no path to the light. It's a classic 2nd in a trilogy

Great read! This is the second book in the series and it is just as good as the first. The story is compelling and the characters really draw you in!
