Lady Isabella Collingwood was once known for her untamed spirit, cherished only by her twin brother and his closest friend, Simon Lyndon. To them, she was perfect as she was. Her parents however saw fit to exile her to Ireland, hoping to refine her into a proper lady. After five long years, Bella returns, but she's no longer the wild child she once was- not to the eyes of others at least. When Simon's gaze meets hers, she wonders if he still sees her as the girl he once knew…

Could it be that the wild Bella, and the tenderness she once shared with Simon, are forever gone?
