Query: Thriller with phychological and multiple plot twists

My awareness of the intricacy of Rick Riordan's plotting began when I realized the main character was known only by his last name. This interesting linguistic twist indicates a distancing from intimacy and immediate knowledge about Chadwick's personality and history. I should know. I semi-dated a man who constantly referred to himself by his last name. The story is riveting and often doubles back to re-involve the original characters and reveal previously unmentioned details. I pre-ordered this book and will always pre-order this writer's novels.
