A top, workaholic lawyer. An independent, ambitious marketing executive. Neither was looking for anything more than a hook-up, so what happens when a hook-up leaves them hooked - on each other? Jackson Callaghan leads his family's London law firm by example: work hard then work harder. Surrounded by his six siblings he's never needed the commitment of a relationship and is more than happy with his poker nights, occasional one night stands and owning the roads on his Harley until he meets Vanessa Moore. Vanessa has no interest in anything other than growing her marketing company and breaking all ties from her ex. The contract to rebrand Callaghan Green is her chance to showcase her talents, not end up in Jackson Callaghan's bed, on his kitchen work top and his sofa, amongst other places. He's rearranging her world and she's not sure she doesn't like it. But can two independent, ambitious workaholics ever manage to work things out for each other, and with something possibly more important at stake: their hearts? Engagement Rate is the first in the Callaghan Green series. Each book is a standalone and can be read separately from the others.
