Ava Lee is a Chinese Canadian forensic accountant who’s in business with an Uncle in Hong Kong and together they track down embezzled money and return it to its rightful owners. They are quite successful, partly because of Ava's social-engineering skills, and partly because both Ava and Uncle have enough muscle (literal and figurative) to encourage the wayward to change their minds. In this case, Ava traces money from a fraudulent shrimp deal through Hong Kong to Guyana, and attempts to make the thoroughly corrupt government work to her advantage.
The plot was believable and the book is well worth reading. There are now about half-dozen Ava Lee mysteries and if you think you may like to try them head to your local branch and request a copy!
