Hi. CMYK and RGB are physically different concepts of colour mixing (subtractive/additive) and the only way how to achieve good results is to calibrate the monitor and the printer (which is hardly achievable in home conditions). Usually DTP professionals are equipped for such kind of work. Even then, the results could be slightly different as the whole colour space is not achievable by only several (4 at least) pigments. And also colour is not simple thing but basically a process involving light, target and person who perceives it.
If you insist on achieving good printed results, the best way is to print it and adjust colour(s) to be pleasing. However you cannot control others so if anybody prints your book he hardly get the same result as you.
