Hanastrew, while Eileen’s protégé, is very much her own fairy and is able to do things with a wand that would make most people’s eyes water and even Eileen herself raise an eyebrow a la Jeeves in admiration. Hanastrew is honourable, loves her food, works out vigorously so never puts on weight, and fights well with all magical weapons (and a good few that involve fists and so on). Hanastrew can’t stand snobs so finds L’Evallier difficult to get on with though she recognizes he is honourable in his way. Eileen is very proud of her protégé and sees it as a success that almost everyone will cross the universe rather than get involved with a quarrel with Hanastrew. Hanastrew adores chocolate (which is one very good reason to like her as a character!).
AND WHAT I DISLIKE!
Hanastrew can be very intense and once set on a path it is difficult to get her off it. That has some advantages. She won't give up when pursuing the enemy for one thing but it also makes her difficult to work with. She doesn't find it easy to accept others have good ideas (the only exception here is Eileen and that's because Hanastrew has always admired and respected her mentor).
