Ada Hopper has been extremely inventive ever since she was little. There was nothing that a rubber band and some tweezers couldn't fix, no question that couldn't be answered by scouring the library, and no way she wasn't escaping over that backyard fence! Ada loves reading and writing because of all the fantastical worlds a good book can bring you to. When not working, Ada enjoys karaoke, spending time with her family, and going on the occasional adventure or two.
