The House of Grenville by B. Green (Silk and Silver series)

Grenville University is the most prestigious in all of Britain, and only those with families of the elite and most powerful stand any chance of attending.

Until now, when a new scholarship presents a golden opportunity for one Louisa Garrick.

Louisa believes delving into her studies and making nice with Grenville’s affluent students will bring her one step closer to achieving her goals—including getting her father out of prison.

But when the heir to the University, Benjamin Grenville, offers her a unique proposal, she drifts from her path. The chain of events that follow will change the way Louisa sees the world forever as she stumbles upon a secret that threatens the entire Grenville dynasty.

Will she keep it to herself … or use it to her advantage to make all her wishes come true?
