Take John R's suggestion, while looking at all of Nikon's DX 18-xxx options. They have different prices, focal length, and sometimes plastic vs metal mounts. They're all equally sharp, VR enabled, and well matched to the DX bodies. Hopefully, more focal length on the 'wide end' will be a welcomed change for your wife's shooting style.
18-105mm VR DX
18-140mm VR DX
18-200mm VR II DX
18-300mm VR DX
This is good advice. Another option would be to look for a nice used 24-120mm f/4 G VR zoom. I paid $425 for mine at my local camera store a couple of years ago. (I did have to find my own hood for another $25.) They may be a little more expensive than that now. You want one with VR in gold letters on the lens.
