Assuming your aircraft is equipped with a good radio and an artificial horizon, this book will give you the basic IFR skills needed to get out of trouble.

Skills covered include appropriate control moves, a workable instrument scan sufficient to maintain level flight and to make a 180 degree turn to safer condition, recognition of attitude problems, and communication with ATC for help.

Also covered is dealing with inevitable stress levels which will be encountered when suddenly entering these conditions.

From The Introduction:
IFR for VFR Pilots is not intended to groom you for an instrument rating; it's not intended to provide a means of skirting around the law when weather conditions are less than legal, and it's not a panacea for every type of weather related emergency you might encounter. What it is, in its most basic, grass roots, fundamental way is a backup flying technique to help see you through this unhappy situation. It's a way to buy some time while you contact Air Traffic Control for help. And when that happens, it's a means to an end. ATC's best efforts are worthless if you can't comply with their instructions.
