"__ Twist, Scientist": kid-lit bestseller (3)

I believe the answer is:

ada

(Other definitions for ada that I've seen before include "Woman" , "- Lovelace, Byron's daughter & computer pioneer" , "Girl's name, one letter short of a man's name" , "-- Lovelace, pioneer in computing" , "Programming language" .)

I've seen this clue in the LA Times.
