Bought For the Frenchman's Pleasure by Abby Green

I read this one recently too.  Here's my review just to chime in my opinion. 

Very good story.  The hero is a businessman who requires a model for his campaign.  The heroine is the same model he publicly called a drug user 8 years ago.  (She wasn't using drugs, and he ruined her reputation)  He thinks she's a drug user and he's reluctant to employ her, but then he decides that her being a recovering drug user is actually a good message to send with the campaign.  They work together, passion hits them.  He suspects her of using drugs again, after he had started to believe she was innocent of it.  She has to deal with her issues about what really happened 8 years ago, it wasn't what he thought but it's been haunting her.  A very good book, great chemistry, the heroine is believably innocent.  Rating: 4/5 stars, a good read
