Adios, Amigos is the ninth and final book in the Asps series, and Jim Scott Book #18. In this book, the members of the team, knowing the end of their time together is drawing near, start making plans for their futures. During the course of the book, Drew and Boris head off to Bolivia on a tip, while the Asps and their British friends take on a mission to Somalia. While in Somalia, they unearth information leading them to Afghanistan, because of the information obtained. Intelligence gathered in Afghanistan leads them to Bolivia, seeking a terrorist they learn of in Afghanistan. Their continuing mission coincides with what Drew and Boris have been up to. At the conclusion, there is a two-series (Janitors and Asps) Epilog. Even with the days dwindling before the team is disbanded, they manage to find plenty to do. Though they do have one member leaving the team early on--while acquiring another member of the plane crew--quite a bit is accomplished...including dealing with information about a major al-Qaida offensive planned for the United States.
