from the back cover
Three years of strife have passed since Kale and Bardon freed Paladin's knights. Now, fiery dragons scorch their beautiful countryside as an evil husband-and-wife wizard duo fight for supremacy. The people of Amara just want to be left alone, hoping the conflict will disappear. But Paladin is dying, and Bardon and Kale--now married--must accept fateful, separate assignments if their land is to survive. Can their efforts turn the tide against their adversaries?
Kale's responsibility is to find, hatch, and train an army of dragons by working side-by-side with the dragon keeper father she has never known. As the Amaran countrymen seek escape, she must gain a greater understanding of her gifts to overcome her doubts.
This one just didn't do it for me. The cover art isn't the greatest (which is highly uncharacteristic), and I didn't enjoy the story nearly as much as her other novels.
We started off on the wrong foot when, on the first page, I discover that Bardon and Kale are married. THERE COULD HAVE BEEN AN ENTIRE BOOK BETWEEN THREE AND FOUR. Gosh, sorry, I don't usually use my caps lock key. But I was quite angry. And then she rubs it in my face by using the words "wife" and "husband" about fifty times in the first chapter alone.
Since Bardon and Kale receive separate assignments, the chapters alternate between them, which is a style that, while necessary, drives me nuts. (side note: I like commas)
Conclusion: Read the book, because it is good (but not great) and necessary for understanding the final book in the series, which you do want to read. It has its moments, I promise!
