BOOK REVIEW- WANTED (The Marshals of Maverick County Book 6) by Delores Fossen

A woman he's never met is carrying his child in USA TODAY bestselling author Delores Fossen's The Marshals of Maverick County miniseries 

When U.S. marshal Wyatt McCabe tracks his target to a Texas ranch, he isn't the only one with Lyla Pearson in his sights. But Wyatt has a powerful reason for keeping the beautiful CSI director out of the line of fire—he may be the father of the child she's carrying. 

The mother-to-be doesn't know who to fear more—the gunmen surrounding her house, or the stranger claiming paternity of her in vitro baby. Holed up together at his family homestead, Lyla struggles to fight her attraction to the sinfully handsome lawman. But with a killer stalking them, it may tear their new family apart….AMAZON 4 STARS

This book had plenty of action and mysteries in it.  In fact, even the beginning chapter opened up right into some pretty dramatic action. 
Wyatt and Lyla were both good main characters who started out with some really big trust issues at first.  There was plenty of danger going on so they were right about  being cautious.  There is a romance that develops between them because of their attraction to each other.  But more focus was on the threats, danger and attacks against them and the family.  They were just trying to stay alive will they figured who was behind it all.  There were plenty of people to look at and also some false trails to sort out. 
Wyatt had a large family that included foster brothers who also were federal marshals.  You don't always see that happen in a book but it was handled well. 
One thing that I found a bit irritating was the overuse of the word, "Mercy" in the way someone responded to an emotional thought or action.  

The villain is found out, lives saved and a H.E.A. for Wyatt and Lyla.  What's not to like about that?
