Derrick Ashby just posted a nice review of The Fallen Sun on Goodreads:

This is an excellent book. It’s got interesting technology, good world building, a collection of characters that you care about, and some mysteries that keep you reading to the end.

“The Fallen Sun” is well worth reading, particularly if you like science-based science fiction.

Here’s a link to the full review on Goodreads.

Note that there are a few spoilers in the full review!
