Courted by a Cain 

Cooper Larson doesn't care about finding Hollister Cain's long-lost daughter, even though a huge inheritance hangs in the balance. As Hollister's illegitimate son, the renegade snowboarder broke away and made his own millions long ago. So when his former sister-in-law Portia Callahan insists she's spotted the missing Cain heiress and solicits his aid, it isn't money that motivates him. It's his long-forbidden hunger for Portia. So he agrees to help if she'll collaborate on an event to finance his latest venture. With Portia finally within reach, he quickly melts the cool society princess's resistance…but will the barriers that kept him a black sheep before get the better of him now?
