The Spare Man, by Mary Robinette Kowal

Tesla and Shal are enjoying their luxury honeymoon cruise to Mars when it is disrupted by a brutal crime. With her spouse framed for an apparent murder, it will take all of it-girl Tesla’s power, money and ingenuity to keep him safe and clear his name. Living with chronic pain after an industrial accident seven years earlier, Tesla and her usefully cute service dog have a lot to navigate in this interplanetary murder mystery. As the body count mounts and the shipboard security team proves less than helpful, celebrity robotics engineer Tesla and her former detective spouse must call on all their resources to make it to Mars. The tale provides interesting glimpse into a possible future where gender neutral is the norm, people of all genders knit, crochet and embroider for relaxation and cocktails are king. The finer plot details get a bit lost in the science, but its largely an entertaining read.
