Zig Zephyr and the Forever Diamond

What would you do with a billion dollars?



That’s the exact question Zig Zephyr asks himself when he inherits his family’s fortune. 

But money isn’t the only thing he inherits. 

Zig also gets his grandfather’s coded journal … the same grandfather who died escaping from the world’s most famous prison after being convicted of stealing the priceless Forever Diamond. “Save the family!” his grandfather scribbled. “Build the machine!”



Zig quickly unlocks the journal’s first riddle and discovers a secret lab on his family’s estate, where he finds plans for his grandfather’s greatest invention: a time machine.



Zig and his friends soon embark on a journey through time that takes them to battlefields and beaches, inventors’ labs and the cradle of the American Revolution. 

But can unraveling his grandfather’s impossible riddles across the centuries finally reveal the fate of the Forever Diamond? And will Zig ever be able to come home again?
