Sanctuary, Inc. #2

Under the Radar

Rate this book
No one is who they appear to be. Not even the enemy.
Baltimore social worker Mo Reardon is dreaming of a margarita, a manicure, and a beach vacation. And it wouldn’t hurt to understand why the most sizzling man she ever met ghosted after her best friend’s wedding. But one phone call to the police changes everything. She’s running for her life.
Commander Mac Mackenzie is a discriminating hunk of hotness. His arms have held rifles and women from around the globe. But the one woman who locked and loaded his heart over a pool table isn’t interested anymore. That is—until their lives collide under unusual circumstances.
As their romance heats up, an enemy lurking in the shadows plans to eliminate them. The men and women of Sanctuary, Inc. have one chance for a rescue. Minutes count. Will they make it in time?
Let the fireworks begin! Anything can happen when you’re living under the radar.

A great read

Mo and Mac went through enough for several couples to overcome. But to find out who was behind it was sort of a given. Always for the money.

Omgosh even with all the crazy ...

Whom would not love Mo? She was so fun, engaging, totally a kick azz woman, with great taste in men and shoes!
Mac, Mac, is the perfect compliment for this kick azz woman! Even when the insanity seems to be winning, unflappable and totally about getting his Mo!

Best ending ever!

Next !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

UNDER THE RADAR caught me by surprise! I picked it up because I was intrigued by the description (and the cover was pretty enticing), but the author is new to me, so I wasn’t sure what to expect. If you’re wondering whether this is worth your time, trust me, IT IS!! This is a fast-paced, intriguing read filled with excitement, drama, and so many twists it will often have you on the edge of your seat. And the chemistry between Mac and Maureen is very compelling and their passion is off the charts. But what makes their characters so believable and their tale so engaging is that you can see how they work as a couple. Between their quickly developing relationship and the steadily building suspense and gripping threats of danger, you will become so deeply immersed in the story that you won’t want to put it down. This is one of those tales that will keep you reading late into the night so be prepared to lose some sleep! I guarantee it’s worth it!!

Although Mo's story starts on the gritty streets of Baltimore, she soon escapes danger by boarding a cruise ship at the city's port and setting sail for the Caribbean. Danger, however, has a way of finding her. So does dreamy Mac, a security specialist totally into the woman with whom he shared one unforgettable night.

Under the radar is a well-paced, delicious romantic suspense with trouble everywhere Mo goes. Loved spending a few hours aboard a cruise ship. Couldn't help myself turning page after page hoping her enemy would be found and true love would blossom. So good--and it didn't even matter that this was the second book in a series. Wonderful all by itself.

It was so good! I love the adventure and laughs that I have gotten from it! (I even enjoyed the sex parts, I may need to visit a new lingerie place! LOL) It was very relaxing and enjoyable to read!
I have added you to my favorite author list with Lisa Scottoline, James Patterson and Jodi Picoult!
I look forward to reading the next book!

Another 'soft', enjoyable read.

This is the second book in this series, and although the tension of each incident wasn't there for me, I wanted to stick with it as I was enjoying the general flow of the story line, and I just loved the banter, priceless.
