Good books on writing music for keyboard/harsichord/piano in the baroque period

Are there are good books out there on writing piano/harpsichord music from the baroque time, like writing a suite or something. I'd like it to cover the harmony of 2 parts because my "Anne Butterworth:harmony in practice" is for SATB.

I love the baroque style, especially solo piano pieces.!

thanks,

will

I think that the basic rules for two-part harmony are the same as rules for a soprano and bassline. I could be wrong.
