Do No Harm

When Todd's critically damaged ship dropped out of hyperspace near the Human colony world of Azure, he had no memory of his past. He didn't know who he was, or even what he was, and the Humans didn't either. That didn't stop the colonists of Azure—they took him in, anyway…even though they didn't understand how he could do some of the things he could do.

Todd and his descendants consider themselves Human—eight armed and water-breathing—but Human, nonetheless. After seventy years living among Humans, Todd's descendants are going back out into the Union to make their mark—from fifteen-year-old Verne, who's a little short to be a mercenary, to Harryhausen, who wants to be the most famous PI in the galaxy. Eventually they learn that the rest of the Galactic Union knows them as Wrogul, intelligent octopus-like beings known for science and the ability to perform surgery like no other race can.

These Wrogul do more than just practice medicine, but they still intend to do no harm. Unfortunately, the Humans, whether they have two arms or eight, have powerful enemies... and the Wrogul may have no choice.
