Gaia (Guy-ya) Stone is following in her mother’s footsteps. She has been training to be a midwife for years and is ready to accept her role in the community. For as long as she can remember, life on the outside of the wall has been this way. The first three babies of the month are advanced to the Enclave to be adopted and live their life inside the wall. While the pain of losing a child is great, the mothers know their baby will be living in a community with conveniences not available to the people living in Wharfton like electricity and running water.Gaia doesn’t know what to do when her parents are arrested and taken by the Guard of the Protectorat. She finds it hard to believe that her parents know anything the Enclave would want to know, but by the questions they ask her when she comes home to find them gone, they think her parents have important information. Gaia is completely in the dark. The only thing she has to go on is the long piece of ribbon with a strange code sewn in it that her mother’s assistant gave her and told her to keep secret at all cost.Gaia’s life becomes a complicated game of cat and mouse as she attempts to get inside the wall, find her parents, and solve the mystery of the coded ribbon.Caragh M. O’Brien has written a wonderful addition to the dystopian genre. Readers get a glimpse of life in the 2400’s after a drastic weather change has drastically reduced the human population and even though the world is completely different than the one we live in, the problems Gaia encounters are very similar – she enjoys time with her family, likes socializing with friends, and is insecure when it comes to love.BIRTH MARKED is fantastic. I loved it and stayed up much too late because I couldn’t put it down. It definitely deserves my Stay Awake Award. The author leaves the ending open for a sequel and I for one can’t wait to see what happens.
