Query: Yesterday's Promise

In this novel were blood is not thicker than water, Rogan Chantry finds himself in a fierce battle with several relatives, and tribes in South Africa over diamonds, gold, and a treasure map.I found it difficult to have any sympathy for any of the characters involved. They all seemed to be very greedy fortune hunters. Even the main character, Rogan showed few Christian values. He was willing to leave his love, Evy Varley behind in search for his riches.At certain points the book was very interesting and quite a page turner and other times the novel was bogged down with too many characters and didn't seem to have much relevance to the story. In the books defense, this was book two in a series, and maybe those characters had more relevance in the first book.
