Mile High [#2] : Up in the air/ R.K. Lilley.
(Book)

"James has initiated Bianca into a dark and drugging world of passion and pain. He taught her about her own submissive, masochistic nature, and she fell swiftly and deeply in love with the undeniably charming and impossibly beautiful Mr. Cavendish, but a painful misunderstanding and the return of the brutally violent demons of her past have combined to overwhelm Bianca, and, confused and hurt she pushes him away. It's been over a month since the shocking attack that hospitalized her, and since she told a distraught James that she needed space, but her feelings haven't gone away. Even she know that is was only a matter of time before he would cast his spell on her again" --from back cover.
