Jenny Holliday is the Mojave's machine whisperer-a brilliant but socially awkward tech specialist who treats her equipment like cherished companions and sees broken things as puzzles waiting to be solved. At 25, she's established herself as the go-to repair expert in the region, traveling between settlements to keep water purifiers running, generators humming, and defenses operational. Her modified laser pistol Spark represents her technical genius with its devastating Overdrive mode-a cutting laser that requires a fusion core and burns through 1% charge per second. She treats using it in combat as a last resort. Jenny values independence over security, turning down recruitment from every faction to maintain her freedom to teach and help anyone who needs it. Set in the Amberverse-same Mojave Wasteland as Amber Wild, Alain, Ruby's Caer Paravel, and Barbara's Camp Golf.
