Amber is the belle of the current London season until an unexplained (seeming) illness strikes (with Alopecia universalis, a condition characterized by the complete loss of hair on the scalp and body) although at the time of this story is not really known about and so no one can explain it and she is shunned by the very society that adored her.
I thought that I wouldn't like Amber's story because she seemed so selfish when she was "the belle of the ball" but through living in "exile" she becomes a better person and ends up with Thomas (who at one point helps her out through a very small act the very night society shuns her). Thomas was such a sweet person. The romance aspect is more in the background so I wouldn't quite call it a romance but was a great story nonetheless.
