Can anyone recommend

any really good books on plotting?  I'm thinking that it was time I was plotting another historical novel, so that I can finally send Running Press the option book that it calls for in my False Colors contract.  Not wanting to do anything the easy way, I made up the plot for False Colors by doing one of those "100 drabbles from random prompts" things, and it took me the better part of a year just to do the plot plan as a result.  This time I was hoping to do something a bit speedier!
