The Cydonian Pyramid: The Klaatu Diskos, Book 2

Common Sense Media says

Complex time-travel follow-up focuses on new character.





What parents need to know

Educational value

When they enter the diskos, characters travel in both time and space, and, when Tucker or Lia find themselves in the historical past, it's described accurately.

Positive messages

Loyalty is important, and people need to look out for themselves and each other. 

Positive role models

Both Tucker Feye and Lah Lia are resourceful, determined, and brave. In the face of great danger, they maintain their cool, and when they have to fight back, they're never needlessly cruel.


Priests at the pyramid stab their sacrifices with a dagger and wield weapons that can cause a victim's head to explode.


Lia is sexually harassed by the son of her foster parents.


There's very little swearing; "damn" and "hell" are each used once or twice.

Not applicable
Drinking, drugs, & smoking

One of the antagonists is a low-level drug dealer. Tucker's Uncle Kosh drinks a lot of beer, both as an adult and as an underage teen.

Parents Need to Know

Parents need to know that The Cydonian Pyramid mixes science and fantasy with religion. It includes scenes of human sacrifice and battles in which victims have their heads blown off. The language is generally mild, with one or two uses of "hell" and "damn." One antagonist is a low-level drug dealer, and one of Tucker's family members drinks a lot of beer, both as an adult and as an underage teen.

What's the story?

In the second book of the Klaatu Diskos trilogy, the focus shifts away from Tucker Feye, the protagonist of the first volume, to Lah Lia, a pampered girl in the future who's destined to be sacrificed on the Obsidian Pyramid. When the ceremony is interrupted by the appearance of a mysterious boy, Lia takes her chance to escape. She ends up in a different time and must adapt to a new set of societal rules. Meanwhile, Tucker continues to track her from one portal to another.

Is it any good?


THE CYDONIAN PYRAMID avoids many of the problems of second installments by shifting the focus onto a character other than the first volume's protagonist. Lah Lia is very different from Tucker Feye, and her adventures do more than mark time until the third volume arrives. Keeping track of all the timelines and characters may prove difficult for some readers, but there's a strong sense that everything will come together in the final installment -- although the plot is anything but predictable.
