The Artemis Project — Vivian L. Holt

The government has created the perfect assassin in the cold, calculating Katrina James (Code Name: Artemis) who always did as she was told. Then the case of Robert Markum lands on her desk, sending Katrina into a tail spin as she uncovers the truth about her own conception. Now everything she believes comes into question as a father races against the clock to save his daughter.
