It has taken some adjustment, but Nita Graus has made quite a home for herself among the crew of the Wind Breaker. Under her skillful care it has become one of the only airships to stay aloft without the continuous repair and oversight of the vile and manipulative fug folk. Word of her adventures with Captain Mack, Gunner, Lil, Cooper, and Wink has made the whole crew into living legends among the residents of the mountain towns of Rim, but in doing so it has also made finding safe harbor virtually impossible. Agents of the fug folk and those working on their behalf hide in every cloud and skulk in every shadow. Only one town, a place called Lock, is willing to welcome the Wind Breaker into port. Most of the townspeople have already been shunned by the Fug Folk, and as such have little to lose in aiding and abetting the crew. Captain Mack, mindful of his advancing age and the risks he's had to request of his crew time and time again, has begun to plan for his retirement. Plans are swiftly derailed when the fug folk hatch a plan of their own, splitting the crew and locking Nita away in the floating prison known as Skykeep. Skykeep is the second book in the Free-Wrench saga and continues to chronicle the adventures of Nita and her new crew as they continue to clash with the twisted figures who control the destiny of a continent.
