The Sparrow is the name of the ship that was captained by Carolina. It had been a part of the Spanish Armada, but after the Day of the Shadow ended, she and Diego de Leon stole it from the fleet. Aboard the ship are the entire crew of CaptainHawk, including his nephew, Tim Hawk. Captain Hawk was tired of being a captain and decided that he only wanted to be a surgeon aboard the Sparrow instead of the captain.
Jean Magliore also joined Carolina and Diego on their new vessel to travel to India where he would be free to reunite with Lakshmi, for she had served for all she needed to at Sri Sumbhajee's palace. Diego remained first mate on the Sparrow and Carolina served as captain as she'd always dreamed of.
