(CNN)Anais Bordier and Samantha Futerman have the same laugh and the same freckled cheeks. They wear their hair the same way and have since they were babies. They share a hatred of cooked carrots, a love of the same color nail polish and the need to sleep 10 hours a day. The pair tease, poke and prod each other like they've grown up together, but they didn't. Neither woman knew she had an identical twin sister until less than two years ago. That's where the power of the Internet, a lot of luck and a series of "what ifs" enter the picture.

In a new book "Separated @ Birth," the sisters document how they found each other

The sisters hope their story will help other adoptees reunite with family
For @placeholder, an only child, discovering she had a sister was amazing, but realizing that she had a twin was "even crazier, because you have so much in common."
