Not your grandma's gray-haired ex-FBI agent
Brigid Quinn thought she left the past behind when she retired from the FBI. No longer young and blonde, her undercover days of posing as bait for human traffickers and sexual predators are over, and as her 60th birthday nears, she's enjoying adding to her rock garden and learning to cook for her new philosophy professor husband. However, when an open case that has haunted her for years looks like it may finally close with a full confession from a serial killer, she can't help but return to her old investigative ways when a bright young agent asks for her help in proving that the confession isn't as authentic as it seems.
Not only is Becky Masterman's debut novel unique because of its unconventional heroine - an older woman who isn't grandmotherly or soft in any way - it also stands out because it's just really good. Masterman does a masterful job of evoking Brigid's Arizona home, and the plot is wonderfully unpredictable without deliberately manipulating the reader. And of course, Brigid herself is pretty fantastic: emotionally scarred and closed off due to her dangerous past, but still vulnerable and empathetic, and willing to put herself back in danger in order to discover who really killed several women along Route 66 all those years ago. Oh, and that killer - definitely not who I expected.
