Colton Undercover (The Coltons of Shadow Creek, Book 2) by Marie Ferrarella
On the hunt for escaped criminal mastermind Livia Colton, FBI agent Josh Howard knows just where to start: the fugitive's family. Namely, Livia's eldest daughter, Leonor Colton, who was very close to her criminal mother. Could the alluring museum curator be hiding the Colton matriarch? Maybe.
Undercover as a billionaire art collector, Josh is invited into Leonor's life. He's surprised to find that the heiress, betrayed by an ex and at odds with her siblings, needs a strong shoulder, and Josh is all ears. But when an attempt is made on Leonor's life, Josh finds his cover is about to be blown - along with his unexpected true feelings for his Colton connection.
