This series was AMAZING! It was a murder mystery on the moon. I can never turn down a good, realistic si-fi PLUS murder mystery. It has it all! It was placed in 2040 and their second in command had died. He had walked out the airlock (to the moon’s surface) with his space suit on wrong- he died in seconds. Everyone thought he had gone crazy, but Dashiel Givson suspects different. Murder. The first book is almost mirrored in the second- the base commander this time disappears. With just enough breaking the rules, they can figure out where she is- and who did it.
