The Truth about the Rogue by Rose Pearson

A scandalous marquess. A hidden passion. When Charlotte discovers the man behind the love poems, will she run—or risk her heart?

Andrew, the Marquess of Kentmore, has a secret. Despite his roguish reputation, he writes poetry about love and sends it anonymously to the London Chronicle. Believing that no one will ever know it is his work, Andrew throws himself into society, intending to marry no one but flirt with as many young ladies as he can.
Charlotte Hawick does not much like society. Quiet and retiring, she prefers to reading to dancing though her mother insists that she attends every single society occasion! The poetry from the London Chronicle catches her attention, however, and Charlotte begins to daydream about the writer of such beautiful words, wishing desperately that she could meet him.
When a sudden collision knocks them together, Charlotte finds herself bound to the very worst sort of gentleman. When a chance comes to free herself from him, will Charlotte take it? Or will certain truths hold her back and tie her to him forever?
