Liz Cantrell promised her dying father that she would take care of her younger, head-in=the-clouds sister. Now she is in real trouble because she has been kidnapped and Liz thinks her new brother-in-law is involved. Flying to Niagara Falls to deliver the ransom demanded when she is detained by ICE agent Blake Fallon. Liz is a mild, meek, and usually scared of her shadow type of person but to save her sister she will do anything, even go up against Blake Fallon. She thinks the agency he works for describes his personality to a tee, but as they spend time together she discovers that there is more to Blake and she likes what she sees. Blake has to play the tough guy when he first meets Liz but he feels an immediate attraction, but he has strict rules against associating with anyone under his suspicion or protection. He eventually finds out that some rules are meant to be broken. I enjoyed this book as much as I have enjoyed the previous three books in this series and would recommend it and the whole series.

This is book #4 in the Northern Border Patrol series. Liz Cantrell has been awoken in the night to a thief in her home. Shortly after she receives a phone call asking for a ransom for her sister Jillian, who is on her honeymoon with her new husband Travis. Apparently Travis stole a valuable necklace of uncut diamonds from an international criminal named Idris Santini. Santini has taken Jillian and will release her upon receiving the necklace. Liz will travel from her home on Hilton Head Island to New York to take the necklace and rescue her sister. At the airport she is pulled aside by Blake Fallon, a US Immigration and Customs Enforcement Agent, and Nathanial Longhorn, a Canada Border Services Officer. They want Liz to cooperate with them in bringing down Santini. Blake has a personal reason for wanting to bring Santini down as Santini killed a fellow officer and Blake feel some responsibility for that. They will also have to contend with Ken, the man who broke into Liz's house, as he is also after the necklace. Liz will have to put her faith in Blake in order to rescue her sister. She will also depend on her faith in God to see both her and Jillian through this safely. Neither Blake or Liz are looking for a relationship but they develop feelings for each other along the way as Blake's job has him moving around a lot and Jillian's life is running her antique shop on Hilton Head Island.

I haven't read the other books in this series but this read just fine as a stand alone novel. This was a quick read that held my attention throughout. I liked the characters who were easy to relate to as they had real life problems. Both had trouble trusting and neither wanted a relationship. Liz was dealing with a previous relationship in which she lost her own identity so she doesn't want to get involved again. Blake's life is his job and he had a previous relationship in which he was lied to so he has trust issues. I liked Blake's fierce need to protect Liz and it was nice to see her a bit vulnerable at times despite her independent and strong willed nature. The storyline flowed smoothly being told from the viewpoints of Liz and Blake. I really liked how it ended and look forward to reading the other books in this series. I really hope the next book will be Nathanial's story as he was one of my favorite characters in this book.

I received a digital version of this book free from the publisher, Harlequin/Love Inspired, via NetGalley in exchange for my honest review. ( )
