Book ~ "Death, Taxes, and Sweet Potato Fries" (2017) Diane Kelly

From Goodreads ~ When the IRS is tasked with assisting the border patrol in pursuing unscrupulous “coyotes” who’ve transported illegal immigrants across the border, Tara finds herself at odds. Not only must she investigate Brett Ellington, her old flame whose landscaping business employs such workers, but now Tara has to convince her romantic partner in crime, Nick Pratt, that she doesn’t still carry a torch for Brett.

Now in addition to proving her love to her own fiancé, Tara is on the hunt for a trail of bogus 1099s in the Dallas area. Someone, somewhere is using the IRS as a pawn in a cunning game of revenge. Will Tara be able to identify the culprit making the false tax reports - before her sweet-potato-fry addiction forces her to get her engagement ring resized? That is, if jealousy doesn’t get the best of Nick first.

Tara is a Special Agent with the IRS.  She has two cases on the go.  Someone is transporting illegal immigrants into the U.S.  Sometimes they live in the process but sometimes they are abandoned and left to die.  In the other case, someone had filed false tax reports on contest winnings never won and Tara has to follow the clues to see how the people are connected.

In the meantime, Tara has recently gotten engaged to Nick and they are planning a fall wedding.  Since they are busy with their jobs, they have left all the planning to their mothers.  In any other story, there would be a clash but Tara and Nick's mothers get along and things are progressing well.  She has also developed an addiction to sweet potato fries and a Spanish soap opera.

I've read many books by this author and I liked this one.  I liked the writing style ... it was funny and sarcastic at times. It is written in first person perspective from Tara's point of view.  As a head's up, there is some swearing.

It is the eleventh book in the Tara Holloway series (I've read them all and like this series).  Though it is part of a series, it works as a stand alone and you don't have to read the others to know what's going on.
