Birthmarked is a thrilling, action-packed dystopian by 2010 YA debut author Caragh O’Brien. I was in the mood to read a good, satisfying dystopian and Birthmarked really fit the bill. This book should satisfy those looking for something similar to the Hunger Games with its intrigue, mystery and suspense.The dystopian world is set up very well, with a plausible concept, and the characters are compelling. The protagonist, midwife Gaia Stone, is brave and faces danger at every turn. Her parents kept some secrets from her to keep her safe. However, now that they have been captured Gaia must use her wits and code-solving skills to help save them. I have not read a book with codes before and thought that was an interesting element.The plot is thought provoking regarding the midwives and ethical dilemmas. The midwives have a monthly baby quota to fulfill for the Enclave. I was not sure of the Enclave’s intentions regarding the birth records. It seemed sometimes that their intentions were good in that they wanted to look for a suppressor gene to combat the health concerns plaguing the Enclave. However, their methods were suspect and their jump to imprison the midwives and doctors made them even more suspicious.In addition to the code solving mystery and action, there is a little romance thrown into the mix. Gaia has great chemistry with Captain Leon Grey. Their relationship begins slowly and believably as they learn to trust each other. It is nice to see someone who can look past Gaia’s scars and believe in her.The book is paced very well, and held my interest from beginning to end. The suspense ramps up toward the end and I couldn’t put the book down. There are some surprising twists along the way. The ending is sudden and intense, and sets up a whole new story for Gaia. I can’t wait to read what happens next. Those looking for a satisfying dystopian after finishing the Hunger Games should enjoy this series. Recommended also for fans of YA, dystopian, and sci-fi.Birthmarked is the first book in a trilogy. The sequel, Prized, comes out in November 2011, which is entirely too far away.
