Mars isn't ready for a revolution, but as violence escalates and a prince goes missing, it might not have a choice. Lucy sails to the cloud cities of Venus and finds herself ensnared in a diplomatic incident and investigating a murder. Moira visits her family on Mars, where a populist revolution is heating up and violence becomes a regular occurrence in the capital city. Their love is expressed only in encoded letters…letters that can’t begin to express the depth of their feelings. Will the common people finally make their voices heard, or will it all end in blood?
