The Librarian Principle by Helena Hunting

Annaliese Harper knows that one tiny mistake can jeopardize a career before it’s even begun. Letting your boss find the extensive collection of porn on your personal laptop is one way. Sleeping with him is another. Liese manages to do both.

As the new librarian at a prestigious small-town private high school, Liese is drawn to her sexy, charismatic principal, Ryder Whitehall—an attraction she refuses to acknowledge given their relationship and her recent liberation from a delusional ex-boyfriend.

Liese is certain Ryder’s flirtation is the product of her sex-deprived imagination—until he discovers her digital porn stash during working hours and demands a private meeting. Behind closed doors, their attraction explodes into a dangerous, passionate affair that not only threatens their jobs and reputations, but most of all, their hearts.
