Critical Condition is the third book in Sandra Orchard's Undercover Cops series and a great addition. Having read the first two books prior to this one, I can say that I am loving this series and hope it doesn't end with this book. One thing I particularly like (besides the fact that the cops are undercover) is that some of the previous characters appear in this book. I love that!
The suspense in Critical Condition was great and I could not decide who I thought the killer/bad guy was because there were too many people it could have been. The story was really interesting and I liked the main characters a lot - it was easy to get attached to both Zach and Tara.
There was some romance in Critical Condition too, so that made the story all the more great to read. While I loved the first two books in this series, I think this one may be my favorite, but only slightly since they have all been great. I don't think you'd have to read the first two books to enjoy Critical Condition. I recommend this book if you enjoy suspenseful stories with some romance.
