Well, first of all "VFP Language Reference",
then "VFP Developer's Guide"

then you can continue with, for example

"Object Oriented Technology: A Manager's Guide" by David Taylor.
"Mastering VFP" series (MS Press.)
"Programming Visual FoxPro 3.0" by Whil Hentzen
"Visual FoxPro Expert Solutions" by Miriam Liskin
And, of course, my favourite one: "Microsoft Pros Talk" :)
