Bad (Mad, Bad, and Dangerous to Know Trilogy #2)
Chloé Esposito

When Alvie discovers that her hit man boyfriend has driven off with the Lamborghini and two million euros, she does what any heartbroken, deserted, amateur assassin would do - she drinks everything in the mini-bar and trashes her hotel room. And then she gets to work.
A perilous cat-and-mouse game takes the pair across Rome, leaving a trail of collateral damage in their wake. But as she wholeheartedly embraces her dark side Alvie will have to figure out if Nino is her nemesis . . . or the only man bad enough to handle her.
