I only read when my OCD kicks in

Review Copy of Media provided by NetGalley.

Title originates from Shakespeare's Macbeth:
"Tomorrow, and tomorrow, and tomorrow creeps in this petty pace from day to day, to the last syllable of recorded time' and all our yesterdays have lighted fools the way to dusty death."

This is a fast action packed YA thriller. Definitely a movie in the making.
This story has somewhat of a John Green feel to it... in the romance scenes at least. Combine John Green in "Looking for Alaska" and the movie "The Butterfly Effect" and you will wind up with All our Yesterdays.

The only downside to this book and maybe this is a knock against YA in general but the action is so fast that it makes the character development somewhat lacking. Hard to get to know a person when they are running for their lives from the very first chapter.

The story starts out with Em and Finn buried in a secret government prison cell. Thanks to an earlier back in time event they make a break to travel back in time 4 years to erase creation of the time travel machine and save the future of the world. The mechanism for time travel? A particle collider/acceleration machine that is code name Cassandra. Apparently this is the 14th effort that Em and Finn have made to go back and stop the process which leads to time travel. On this last effort they have to kill the "doctor" who invented time travel. The problem.... in the past the "doctor" is a close friend.

I give this one a 4 star review because like so many YA titles there is not enough character development and world building. With that said this book does a better job in both categories than most YA titles. I would have also liked to see the author delve more into the science behind "Cassandra" although once again YA titles are not known for their intellectual dissertations.
