Kim’s Review


Unknown Threat by Lynn H. Blackburn is a fantastic start to the Defend and Protect romantic suspense series!

This is the first book I’ve read by Blackburn and I was happily surprised by how good it is. The action is non-stop, her relationships are well written, and the religious moments woven throughout the story help to enhance it and don’t feel forced.

Blackburn does a fantastic job balancing the action scenes with investigative scenes and relationships, whether it be co-workers, family, or love interests. Faith is not only dealing with her needy mom and sister, who has some physical limitations, but this is also the first case that Faith is lead on, and a relationship is starting with Luke. So much is going on, but Blackburn handles all these story threads with ease. And the friendship and camaraderie that is between all the members of the Secret Service team is remarkable. If I had a workplace like that (even with my life being on the line), it would be a pleasure to go to work.

I really enjoyed that it wasn’t until towards the end of the book that the mystery started to get solved. I’ve read some suspense and thrillers where the killer is in the first chapter and there is no surprise, but that was not the case with Unknown Threat… the threat stays unknown for a long time.

Already looking forward to book two in the Defend and Protect series!
