If you mean macro... hmmm
90mm tamron
105mm nikon (older model might pushing your limit, but I have one and its very nice)
70-300...
105 sigma (perhaps)
85 f1.8 (not sure if this is what she'd want, but can get nicer close up photos
60mm micro nikon
Depends what she shoots?
perhaps a 30mm sigma f1.4 or 20mm f2 ish ? Bit wider, but gets the photographer closer...
