People never quite know what to make of best friends Owen and Luna in The Accomplice by Lisa Lutz. They appear to be completely mismatched, and yet they've been inseparable since they met in college. Even a murder within their social group couldn't shake their bond, but it certainly left the people around them questioning if there wasn't something more sinister at play between them. When Owen's wife is murdered years later, the police turn their attention to him, but Luna knows there's more to the story. Now she'll have to finally face the secret she has spent her whole life running from.
