Heart Failure is Richard L. Mabry, M.D.'s latest offering in Christian medical/suspense/romance. I've read several of his previous books and have loved them, so was thrilled to read his newest book. Heart Failure follows Dr. Carrie Markham and her paralegal fiance, Adam Davidson. Carrie, while still struggling with the death of her husband and her failure to save his life, discovers that Adam isn't exactly who he said he was. The book takes off into a thrilling ride of death threats, attempted murders, medical mysteries, and, of course, Carrie's renewed faith in God. Both Adam and Carrie must come to terms with life altering situations that have affected them greatly, in their own ways. I won't spoil it, but the ending was definitely a surprise and I didn't see it coming. The book also includes a reader's guide at the end with discussion questions. This is an absolutely excellent book. I read it in two days and had trouble putting it down. It was the perfect blend between genres - the medical situations felt authentic, the romance was believable and enjoyable, and the suspense was page turning. The Christian element of the book was woven in without any awkwardness, and it explored spiritual themes without seeming preachy. I highly recommend this book to anyone who enjoys Christian fiction. I can't wait for his next book to come out! I received a copy of this book from BookSneeze in exchange for an honest review. All opinions are my own.
