Rilla Devane was a Nashville Detective until her father; the Sheriff of a small Tennessee county, is murdered in the driveway of his mother’s home.  She decided to resign and fill out the rest of her father’s term as a way to find her father’s murderer.  A number of months later she still doesn’t know who the killer is, and now there are deaths happening from ecstasy in town.  Rilla’s long lost mother has showed up and the new “writer” in town has her thinking of her needs, not the needs of the job or the town.

Mac Callahan knows nothing but undercover work with the DEA.  The problem is that he keeps getting involved with the women in his cases.  He is now in the middle of nowhere, Tennessee to try to find out who is moving meth labs and ecstasy into the area.  Unfortunately the money looks like it is going through the accounts of sexy Sheriff Rilla.  Will history repeat itself, causing Mac to get shot, or will Mac and Rilla figure out how to work together and satisfy their baser needs?

Too Good to be True is a very enjoyable story with a lot of twists and turns along the way.  The heat between Rilla and Mac is sizzling and Rilla is one determined woman to keep her goals in mind.  I loved how both characters try to prove the other’s innocence in the first part of the book after getting over their apprehension.  I would not hesitate to pick up another one of Marie-Nicole Ryan’s books when I am looking for a good read.
