The Rogue’s Flower by Rose Pearson

Elsbeth Blakely: An orphan who craves independence
Viscount Andrew Radford: A notorious rogue used to getting what he wants
A clash of wills – who will win?
The world always ignored Elsbeth Blakely, given that she was just another young orphan at the Smithfield House for Girls. She was never a part of the bustling world of London Smithfield Market, cooped up inside the great house with no freedom of her own.
However, life suddenly takes a turn for the worse when Elsbeth meets Viscount Andrew Radford. A notorious carousing rogue, Lord Radford sets his sights on Elsbeth to be his latest object of affection, expecting that she will simply fall into his arms as every other lady has.
But Elsbeth is determined to have her independence. Despite being forced into working at the Radford estate, Elsbeth stands up to the young viscount, finding him determined to get what he wants from her.
But, underneath it all, is Lord Radford really the scoundrel that he seems?
When news of Elsbeth’s real family comes to light, Elsbeth finds her whole world turned upside down, with only Lord Radford able to help. One thing is for certain, however, Elsbeth Blakely is not who she seems either.
