The book stars Saira, a 17 year old girl that is rough around the edges and thinks that she can handle anything that life throws at her. I was not a fan of her in the beginning; she was too curt and rude with a chip on her shoulder, seemingly without that one redeemable quality that you find in a tough character. Thankfully, I absolutely fell for the other characters – Archer, Ringo, Mr. Shaw to name a few- and that helped me to keep an open mind with Saira. After getting used to her demeanor, I began to like her take on the world by myself attitude. The story is amazing – time travel, immortals, chases, escapes, romance this book has it all. I loved the history as well. This is a great book for all ages with strong characters, a well developed plot and lots of action that makes it a fast and enjoyable book to read.
