She’s never been one for toeing the line.
Life hasn’t been easy for Finlay Donovan lately, but it just got a whole lot harder. Her nanny and partner-in-crime, Vero, has been extradited from Virginia to Maryland, where she’s facing criminal charges for a theft she swears she didn’t commit.
Awaiting trial, Vero is forced to live with her overbearing mother and nosy aunt. Threatening messages keep arriving at the door, demanding Vero ‘turn over the money… or else’.
But proving her innocence might be an impossible feat. Vero was one of the only people who had access to the cash. And her alibi is an old flame who ghosted her.
With the court date approaching and a mysterious stalker on Vero’s tail, Finlay decides a trip to Maryland is in order. But to sus out the real thief and get home to Virginia fast, they might have to cross a few lines along the way…

The Finlay Donovan series is one of my favorites and I am thrilled that there are going to be at least four more books. Finlay Donovan, mother and author of suspense romance novels, is a fantastic protagonist, never a dull moment in her busy life as she buries and unburies bodies, steals from the Russian mob, and tries to figure out if her neighbour is a killer. In the sixth book in the series, Finlay Donovan Crosses the Line, the problem hits closer to home than ever when her best friend / accountant / live-in nanny is arrested for a crime she’s been running away from for two years.
Vero has been Finlay’s partner in crime since the first book when Finlay was first mistaken for a contract killer and she needed to hide a body, but now it’s Vero the one in trouble when her past catches up with her. When she was in college, Vero and her friends had organized illegal gambling nights, but they were discovered and when the money disappeared, Vero was accused of the theft. She swears that she didn’t do it and Finlay is determined to prove her innocence. I love the close relationship between Finlay and Vero, how not only they completely trust each other, but they are always ready to do anything to protect each other. Finlay travels to Maryland to help Vero and stays at her family home where between Vero’s exuberant mother and aunt, their nosy neighbours, and a boyfriend ready to spend his life on the run to protect her, Vero and Finlay rush to discover the truth. In the meantime, back at home, the handsome and charming detective Nick is experiencing first hand what it is like to be part of Finlay’s chaotic family when he offers to take care of her two lively young children.
Finlay Donovan Crosses the Line was yet another hilarious, addictive, intriguing read and I can’t wait for more adventures!
