Submit (The Dining Club #7)
Marina Anderson

There is one more task to pass. One more until Grace can become a full member of The Dining Club, and ensure she holds on to David's love and lust indefinitely. But she knows it isn't going to be easy - there are several determined to see her fail, and with David torn over what her success would mean for his lifestyle, Grace must do this for herself.
They will test her on everything she has learnt - pushing her body to the limits and into entirely new realms of discovery. But if she doesn't pass, this world, and David, will be closed to her forever.
