The Lair of Anubis. The Project, #20

An ancient papyrus describing the death of Cleopatra reveals the secret location of the lost tomb of Alexander the Great, filled with priceless treasure. Elizabeth Harker sends the Project team to Egypt, to find out if the tomb and treasure still exist. It doesn't take long before people start dying. A secret cult has worshipped Alexander as the Sun God for thousands of years, and they're not about to let unbelievers desecrate his tomb.  They'll stop at nothing to prevent it.
Nick and Selena are getting older, their bodies starting to show the effects of too many battles and too many wounds. With two children to worry about, maybe it's time to quit. But neither one of them is quite ready to give up the adrenaline fueled lifestyle they've been addicted to for years. It's a decision they need to make soon. But first they have to get through this mission, with no guarantee they'll survive.
