And I don't much like any of them, they're all very similar: monster (evil?)and human? woman in t-shirt (angel?) on a vague background.
Can't say I would reach for any of them.
Maybe it's just that they aren't my thing, but it's like looking at four covers for Regency romances, all of a young woman in Regency dress, outside by a stone balustrade, green lawn behind.
