Publisher's Summary

Fifteen years after warring artificial intelligences nearly destroyed Earth, a young woman finds an artifact from that struggle, upsetting a delicate balance of power and dragging her into the middle of a new fight for humanity's survival. 

With a significant portion of the planet covered in heat-absorbing black dust, Earth's biosphere teeters on the edge of collapse. One AI faction is attempting to fix the damage, with huge machines trundling across the countryside sucking up dust and planting grass, while another faction cares only about elevating itself to a higher plane of intelligence and will destroy anyone who gets in the way. 

As the only humans still not controlled by AIs race to build huge orbital habitats so some humans will survive should temperatures continue to rise, a more secretive organization grows in the shadows and idolizes the man who triggered the nano-replicator attacks that nearly destroyed the world. They, too, believe the only way to stop the AIs is to annihilate everything. 

In Nebula Award winner William Ledbetter’s Level Six, one woman has the power to save humanity - if she can survive long enough to use it.

Phenomenal!

Start with Level 5 by the same author. Both are killer hard sci-fi techno-thrillers!!!

As good if not better than the first book

Good character development, even better story. If you like books about AI, snap this one up. Word of caution as well as mild spoiler alert: it does end on a bit of a cliffhanger.

Great listen.

Very engaging. I found it hard to stop listening. The ending left me wanting to hear the next book.

Could’ve but Wasn’t

I was expecting L6 to be a solid follow up to L5, which I thought was compelling, stimulating, and well written. Unfortunately, it wasn’t. Precisely 66.6% of L6 consists of internal dialogue of wish-washy teenage emotion regarding matters of the heart (cringe). Not what I want in my AI sci-fi novels. The rest was just meh. If you’re anticipating a continuation of the action, science, and suspense from L5, then you should also plan on being disappointed. MacLeod’s superb narration is the book’s only hallmark — what that man can do with his voice is truly incredible.

A good listen, but not the first book

I really enjoyed this book, but there were plenty of places where particular storylines were simply stated and not shown. It is a fair follow up to Level Five, but the main plot and the character development wasn't at the same level. Perhaps I'm just a bitter old man who didn't want a coming of age story after the first book was so adult focused. This one seems more like a teen sci fi novel, albeit a very good one.

Similar to first, feels abridged

This book reminded me allot of book 1 - strong writing without a real happy ending. I’m fine with that, but it just feels like so much story arc is missing. Right in the middle of plot and character development, a switch flips and now we are at the end of the book. So much more that could have been built into this adventure.
