Wed him before you bed him

"At eighteen, Charlotte Page made a life-altering mistake. She wronged a man in an impulsive act that she came to deeply regret, though it led her to her present life as Mrs. Charlotte Harris, owner of Mrs. Harris's School for Young Ladies. Unbeknownst to her, that man is now her anonymous benefactor, the mysterious 'Cousin Michael.' His masquerade began as preparation for a devastating revenge, but became a labor of love. Now Charlotte desperately needs his help. Can he save her from disaster as his real self without revealing the ugly secret behind his charade? Or will the mistakes of both their pasts tear them apart forever?"--Publisher's website.
