Lincoln and Douglas have a long history of writing books together. Relatively recently they have started to write on their own.
So far Lincoln has done well on his individual efforts.
At times the plot was a bit formulaic, introduction to new ultra high tech explorer habitat. Oh it runs on methane gas you say? The pipes are threaded all through out the facility you say. Can anyone guess what will happen?
Still a great imaginative Egyptian yarn with some unusual mysticism, for Child at least, thrown in for good measure, all handled pretty well.
