Never Spellbound by Starry Sky. Set after the first movie. Another quirky adventure that only the combined trouble-making brain power of Rick and Evelyn could ever find. No mummies this time around, but there's still plenty of other trouble to find in Egypt. Also, the author uses lines from Elizabeth Peters novels as her titles. In fact, I think this might have been the story that convinced me to read Crocodile on the Sandbank years and years ago when I first found the story.
