In the final book of the trilogy, Roxanne is the target of a sniper for unknown reasons; her mother continues to search for the hidden Irish Republican Army money; and Callahan hunts the escaped killers of his grandfather. The person responsible for setting it all in motion reveals himself and Roxanne has one bullet in her gun. But that last bullet may hold the answer. It could be the salvation of John Callahan, bring closure to her mother's quest, and save her own life... if her aim is true.
