A Duke She Can’t Refuse by Gemma Blackwood

Headstrong Miss Daisy Morton must make a choice: play the fiancée to a duke she doesn’t love, or face ruin.
Daisy’s loyalty to her friends is always getting her into awkward places. Unfortunately, those places include the bedroom of the stern young Duke of Loxwell, where she is caught hiding by one of society’s most notorious gossips.
For mysterious reasons of his own, the duke saves her reputation with a false engagement. There’s only one rule: she can’t fall in love with him.
Simple enough. What are the chances that the true love Daisy has always dreamed of should turn out to be the strict, strait-laced, surprisingly tender duke with a devastating smile reserved especially for her?
Alexander Balfour, the new Duke of Loxwell, lives for honour and duty. The dukedom weighs as heavily on his shoulders as the responsibility of setting an example for his four unruly sisters.
And that honour has sealed his fate forever. A fatal mistake in his past means he cannot fall in love without betraying those he holds dearest.
Even if Daisy turns his world upside down in a hundred different ways, she cannot save him from his lonely penance.
Or can she?
