Reddit mentions of A People's History of the American Revolution: How Common People Shaped the Fight for Independence

Here are some secondary sources worth checking out.

From Resistance to Revolution: Colonial Radicals and the Development of American Opposition to Britain, 1765-1776 by Pauline Maier. Explores the Whig philosophy justifying resistance and the group nature of such resistance.

American Insurgents, American Patriots: The Revolution of the People by T.H. Breen examines the Committees of Safety, though his focus is on the Committees throughout the colonies.

The Unknown American Revolution: The Unruly Birth of Democracy and the Struggle to Create America Nash examines the roots of the class struggle in America. There are some problems with this work, particularly in Nash's characterization of many of the influential men in early America, but I think it's still a worthwhile source to look at the class struggle and how group action impacted America.

The Revolution Is Now Begun
The Radical Committees of Philadelphia, 1765-1776 by Richard Alan Ryerson actually focuses on the various committees in Philadelphia.

As I think of more sources I'll add them here.

This one is quite good and seems to be just what you are after:
