This lesbian romance is very simple with no huge tensions or anything that read false. This was a book I read a few pages before going to sleep.
I would have the character brush up on her French, or be taught a dialect of the language. To go from not being able to order a diet Coke in a café to being able to cinch the sale within a month suggests that Jamie has supernatural abilities with learning languages.
Unless the product is opium, I would have her sell 100 devices before calling her boss and soothing the nerves of investors.
That said, I liked her attitude about life and how she pushes herself.
