What would you change?
Imprisoned in the heart of a secret military base, Em has nothing except the voice of the boy in the cell next door and the list of instructions she finds taped inside the drain.
Only Em can complete the final instruction. She’s tried everything to prevent the creation of a time machine that will tear the world apart. She holds the proof: a list she has never seen before, written in her own hand. Each failed attempt in the past has led her to the same terrible present—imprisoned and tortured by a sadistic man called the doctor while war rages outside. 
Marina has loved her best friend, James, since they were children. A gorgeous, introverted science prodigy from one of America’s most famous families, James finally seems to be seeing Marina in a new way, too. But on one disastrous night, James’s life crumbles, and with it, Marina’s hopes for their future. Marina will protect James, no matter what. Even if it means opening her eyes to a truth so terrible that she may not survive it... at least, not as the girl she once was. Em and Marina are in a race against time that only one of them can win.
All Our Yesterdays is a wrenching, brilliantly plotted story of fierce love, unthinkable sacrifice, and the infinite implications of our every choice.

Review
I didn't know much about this before reading. I wasn't sure if I would enjoy it or not. Of course I ended up loving it! 

This tells the story of Em and Finn. They have returned to the past in hopes of saving the world. But, their past selves have no idea what's going on. And, James will stop at nothing to change the world. 

This did get a little confusing with the past and present characters. But, the characters were fantastic. I loved them to pieces. I loved that they were the same people but with different goals and lives. Finn had to be my favorite with Em coming in a close second. It was cool seeing the older and the young versions of them. I wished for more of the older James but I really enjoyed the young version of him. 

I don't see time travel done a lot. I really enjoy it though. I loved the concept of this story. It was impossible to put down. It was incredibly fast paced and action packed. I loved all the twists and turns. I loved the way the two stories wrapped into one. I thought everything was very well done. I can't wait to continue this series!
