Mars Underground by William_Hartmann. The book was a good read. It is set on Mars, at a time when thousands of people are on the planet, second stage exploration. People are beginning to think about colonization. The book is a mystery, with an administrator, Carter, his friend the resident artist, Philippe, and a newly arrived reporter, Annie Pohaku, investigating the disappearance of a Stafford, an exobiologist who’s one of the longest serving research scientists and explorers on Mars. Stafford had discovered traces indicating microbial life on Mars billions of years in the past.
The book starts very well, but then seems to stall out in the middle. The plot is uncomplicated and feels too bare. The characterization of the protagonist, Carter, is lacking. The description of Mars and the bases on the planet and Phobos are well done.
