hello,
sorry for your frustrations. This is our motherland and though flawed in some areas, its up to us to be its better future. So, welcome back! there isn't really a book as such. the only thing I would say is for you to get a hold of the JAA ATPL questions. many of them come from there. also, the different schools offer classes for conversion. ask around and am sure you will get the best advice for how to go about your conversion if you keep your ears on the ground....
