Oona and friends are off to light the Red Beacon on Moon Yatta. They discovered the beacons have to be lit in order, which is why they were unable to light the Blue Beacon. Jax is taken back to the starball team he played for before and its nefarious owners. Oona and An Tzu attempt to reach the beacon which is covered in machinery. The Mimic is on this planet too in the form of Stan Moon, a powerful individual who controls much of the planet. They must navigate the red maze around the beacon, rescue Jax and light the beacon all while under the eye of the Mimic. 

I love this series and will be sorry to see it end. I enjoy the growth of all three of our main characters. Oona learns even more about sand dancing and creating portals from Zelle, rebel of Moon Yatta. An Tzu becomes less visible, but gains a prostethic arm and leg. And we learn that Jax has merged with a sacred spirit and become more human and less android. Fantastic storytelling and illustrations.
