Red Sky Warning

Will and Laura are a comfortably married couple who are still very much in love. That was a nice change. Their relationship made the sense of danger and urgency very believable. I really liked their banter at times. We also get to see more of Ricky and his wife as they navigate pregnancy and the complications that go along with it.
Sometimes sequels can be stand alone books, but I wouldn't say that about this one. There are places where I think the reader would be lost if they hadn't read Come the Shadows. So, I recommend picking up that one first. As in the first book, this one leaves some unanswered questions. It looks like this is part of a trilogy, so I'm hoping that they are answered in the final book.
This is a well written series and I definitely recommend it. Try it out!
