In Love with the Rogue by Lisa Campell

She was allowed to sleep with him, but not to fall for him.

When Amelia’s husband died, she never would have thought that his younger brother would gamble away his fortune, leaving her daughter and herself with nothing. Desperate to secure their future she knows that she will have to marry again.
But who would take a penniless widow with a child? Only someone too ruined for a wife.
Christopher Lockhart, the Earl of Berkshire is known for two things: his rakish lifestyle and the deadly curse that befalls women who love him. Having only one daughter though, he is in need of an heir.

No woman would consider becoming his wife. Until a charming red-haired widow comes with a proposal that suits them both; an heir in exchange for security.
Amelia should be careful not to fall for her handsome new husband. She might enjoy his attentions in the bedchamber, but loving him might kill her in real.
And if love is indeed behind every corner, then she should learn to walk in circles.
He was her poison; she was his antidote…
