I personally wouldn't look for answers in a book.
Experiment. There is no harm in it sounding crap as the positive side crap... is... you now know what not to play etc...
I probably would start with knowing the triads of each chord with their inversions and how each triad relates to each other.
then add passing tones for the musical side... as step 1.... Then I would extend them to full chords/ then experiment with a few lines for musical purpose... Whilst working on the bread and butter you can still add your favourite jam...
