Heart of Justice (2010) has some of the same flaws as The Kevlar Heart. Typos, language errors and... euphemistic cussing, which is superfluous and has no place in 'Christian' writing.
Having said that, I liked the story-line in both books and kept them on my shelf. And, I liked the books enough to wish for more. Wish granted with the series Abducted, etc. which was much improved and I liked all three books. Perhaps the publisher change made a difference?
