These two books were the first ones that I had read by Frank Peretti and had worn them out loaing them to friends. Now I needed new copies. Typical to his works, you really need to read the first 3 chapters twice to gain all the information that he writes. He sets scenes, introduces characters and situations and you really need a good memory to remember them as the book progresses - but progresses it does, with twists and turns. A battle in the heavens between eveil and good V mankind inherant capacity to evil and good. Great story lines. His other books are also great - the Oath, Visitation etc as well has the Veritas Project series.
