Day 21: Book you've read that was dramatic/angst-ridden (Emo)
The Lost Girl is kind of a future take on Frankenstein. Eva is an echo, a created human. She is the double of Amarra and her sole purpose in life is to be able to replace Amarra if anything happens to her. She has to learn everything Amarra does.
If Amarra gets a tattoo, so does she. The same goes for scars or other permanent changes. When Amarra dies, Eva has to leave the people who have raised her to replace Amarra. She moves across the world to a grieving family who believe that having the echo allows them to keep Amarra alive. Let's say not much goes as planned.
