Hello,
Being from a Hypnosis and Magic background I played around with some amazing Cold reading routines and there are a few things I would recommend... it really depends on how far in you want to go.. whether its a quick novel thing or if you want to really get into their head. On occasions I've moved girls and guys to tears with it... its that powerful but anyway your starting blocks will be as follows
Red Hot Cold Reading by Herb Dewey
Full facts of cold reading by Ian Rowland
Advanced cold reading by Joe Riding
If it is the novel side of things your after then I recommend these;
Mind Games - By Bob Cassidy
Psycholigical Subtlties - by kenton knepper
and theres an amazing audio set called Wonder Words which explores simple mind tricks, hypno tricks and scientific stuides to help you palm/cold read women.
Good Luck and I hope that helps... All of those contain some real gems but it really depends on how deep you wan to go.
