Provoked by a conversation with dd . . . She says there are (almost) no contemporary non fantasy novels with a teenage girl protagonist, that don't involve said girl falling in love as a major part of the story.
So far I've come up with
The Bone Dragon
Saffy's Angel (admittedly published in 2002)
A Dog Called Homeless (but protagonist isn't actually a teenager, I think she must be 11 or 12)
Are we missing anything really, really obvious? In fact, even if you allow fantasy, I can't think of many more to add (Frances Hardinge's novels being the main ones, I think Mosca Mye must be 14/15?)
This isn't really a 'looking to read', more curiosity!
