Staff Reviews

"Max, Kyle, and Emma don't want to live with their crazy grandfather.  After all, he claims to have a time machine in his basement.  But then Emma is kidnapped and the boys discover that the chronal engine is real, and they have to go back in time to save her- not just from kidnappers but from dinosaurs."

— Madeline


When Max, Kyle, and Emma are sent to live with their grandfather, they think their summer is ruined. But after Emma is kidnapped at the exact time that her grandfather predicted, Max and Kyle are forced to believe his story about the time machine in the basement.
     To save Emma, Max, Kyle, and their new friend Petra must take the trip of a lifetime — to the Cretaceous period. Soon they find themselves dodging killer insects, velociraptors, and the terrifying T. rex. Can these three contemporary teens hunt down a kidnapper, forage for food, and survive long enough to return home?

Praise For…

"The short length, breathless pace, and graphic-novel-esque, full-page illustrations might make this one appealing to reluctant readers."--School Library Journal

"There's peril aplenty, but Smith keeps the tone light and easy, making this accessible to younger readers averse to anything truly scary."--Bulletin
