Definately a good start and I already like the character.
Fear of being stole from her? She is a thief. The safest place for things would be in her control I would think. And a key wouldn't be good enough if she is that paranoid. Needs a story behind it, stuff stolen in the past and such. There would probably and elaborate cache of her most valued possessions too since she loves the manuscripts. (Probably my pettiness but I like these kind of details about characters)
The rest is pretty good, I am probably picky because I like the character and want to know more. Got me hooked, now reel me in. Go to Comment
Surnames: Most surnames fall into one of four categories. Patronymic surnames such as Johnson pass from father to son (literally, 'Son of John'). Occupational surnames such as Cook or Miller stem from an individual's livelihood. Topographic names such as Forest or Ford identify habitation. There are also a few surnames that derive from individual characteristics or nicknames...Small and Stern for example.
