The Curse of the Mummy's Heart. The Peculiars, #1

Something is rising in the desert sand, and between two adventurous men. Famous 1920s Hollywood actor Douglas Fitzhugh and his brother Donnie are headed for Egypt on a classic monster movie quest. Their mysterious benefactor, a man they call Grant, has sent them to find a stranded archaeologist, and all they have to go on is a handwritten journal. That's just the kind of adventure Douglas loves, and he never passes up the chance to get away from his studio-driven life.
Charles Angeloff is also on his way to Egypt with a special object his father has asked him to return to the tomb he ripped it from. Charles is just out of university, and when he meets Douglas, he falls hard for Douglas' charm and his worldly ways. As they travel, more men of adventure join them: a cowboy, a rich seminary student, and a librarian. When they're all together, it's like magic happens, and the men all realize they're on a mission to stop the horror that stirs beneath the desert sands, even as that creature sets its sights on Charles.
Will Douglas and Charles lose each other just when they've found what they both think is the man they want to be with forever?
