An Angel's Share - Wren Charles (Book 1)

Jonno Greystone is a morally grey man.

But an unplanned trip to California to chase a thief turns into the ultimate test of his remaining morality.

Following the trail to Ireland, walking into an engagement party late and uninvited, Jonno is brought face to face with consequences of his past actions.
Dr Aoife O’Clery, academic and heiress to her family's whiskey empire leads a busy life in the United States.

Back home in Ireland to run the business and fulfill a family obligation, Jonno Greystone is the last person she expected to show up.
 
As secrets are revealed, and chaos rains down on the whole family, Jonno and Aoife must decide who they can really trust. Can Jonno look past her deception to unravel the corporate theft and fraud hanging over Aoife’s family? Or will he drag them all to the bottom of a barrel and leave her to face the fallout alone?
