I'm looking for a novel I read when I was younger. It was the third of a trilogy. It featured clones and a benevolent alien race known as "The O's". At some point, there is a big clone rights trial where an American revolutionary war figure (possibly Ben Franklin) acts as a lawyer or something. There was a futuristic battle. At the end, the O's show up after being built up the entire book.

Over all, I remember the story as being anti-climatic and disappointing.

Does anyone know what book this is?

It is not "Slaves of the Legion."

This is The Clone Codes by Patricia & John McKissack

The Goodreads review of the story contains numerous references to clones (duh), clone rights, virtual avatars of various famous abolitionists and a benevolent alien species called "The O":

In the year 2170 an underground abolitionist movement fights for the freedom of cyborgs and clones, who are treated no better than slaves

The Cyborg Wars are over and Earth has peacefully prospered for more than one hundred years. Yet sometimes history must repeat itself until humanity learns from its mistakes. In the year 2170, despite technological and political advances, cyborgs and clones are treated no better than slaves, and an underground abolitionist movement is fighting for freedom. Thirteen-year-old Leanna's entire life is thrown into chaos when The World Federation of Nations discovers her mom is part of the radical Liberty Bell Movement.


With the help of some virtual “Custodians” (Ben Franklin & Eleanor Roosevelt & others), Leanna learns some harsh truths about the world she lives in.


The entire thing with the O seemed to have been pulled from a cheesy scifi movie and made the plot way to complex.

    Making it a double? :-o Why not just edit the first answer? (because this way you get double the rep, of course)

  • @randal'thor - Because the first answer is flat out wrong, but could serve as a useful pointer for future searches. If I go for a double-answer and the OP doesn't actually say "this is the right one" and mark it as accepted, there's no useful way for a visitor to determine which was the correct answer. If I delete it or overwrite it then there's no useful pointer. It's not always about rep, my friend.

  • Yes, book 3 of the Clone Codes is the one I remembered! Thank you!

A quick google suggests this is "Slave of the Legion", the third part of the 'Soldier of the Legion' trilogy.

The O's had killed two billion humans. Beta Three wanted revenge. The Mound was in his sights.

"There's no way the O's are going to inherit this world. It's going to glow in the dark first." When squad Beta is sent on a recon mission to Uldo in the Gassies, they find the Omni's--deadly aliens with unstoppable psychic power loose in the wrong universe. In a snowy landscape they discover the Mound, a massive, mysterious structure built by the O's. Approaching, they find the way lined with the impaled bodies of innocent humans.

  • It's not that but thanks. I remember the O's in my story as being beneficial to mankind, not harmful. I'll update my answer.
