Legend of Isis #13: Volume 1 [EPUB ebook] 

Written by the screenwriter from the Legend of Isis film at Paramount, Ali Russell. Jessica and Scott head to Egypt to attend a gala honoring Egyptology. After a mix-up with the hotel that awkwardly forces them to share a room, they meet Moussa Fusani, a leading Egyptologist who invites them on an archaeological dig of a tomb near the Great Pyramids. Unfortunately Jessica cannot bring her case, so she must leave her staff in the hotel, making herself powerless. Moussa traps Jessica and Scott in the tomb, leaving them to face prehistoric problems.
