Hi guys,
Im looking for a romance book a started, possibly from sample. Books starts with the heroine entering a security company to go for a meeting with people who work their, which include her brother his friends, including the Hero. They are at first unaware that she is the sibling of their friend until she tells them. In one of the previous books the H (her brother) thought she was killed by their abusive father.

That is about all I remember, as I only read the sample and bits and pieces of the previous books. Thanks in advance!
