The main sources I have used for the history of ancient Egypt are:
Manley, W, The Penguin Historical Atlas of Ancient Egypt, Penguin, 1996, is a great little introduction to a big subject.
Gardiner, A., The Egyptians, Clarendon, 1961, offers a detailed and scholarly coverage of the subject.
More recent general books on the subject which have been well-received, but which I have not yet read, are:
Shaw, I, The Oxford History of Ancient Egypt, OUP, 2003
Fletcher, J., The Story of Egypt, Hodder & Stoughton, 2015; this is linked to a BBC documentary on the subject
Kemp, B.J., Ancient Egypt: Anatomy of a Civilisation, Routledge, 2006
For an overview of the archaeology of ancient Egypt, I found the following useful (and enjoyable due to its lavish illustrations): Renfrew, C. (ed.), Past Worlds: The Times Atlas of Archaeology, Times Books, 1995, p. 122-3, 128-9, 136-9.
A work on general archaeology aimed more at students, but readable and with very good coverage of ancient Egypt, is Scarre, C. (ed.), The Human Past, Thames & Hudson, 2005, p. 363, 370ff.
For an insightful look at government in ancient Egypt, see Finer, S. E., The History of Government, I, Ancient Monarchies and Empires, OUP, 1999, p. 132ff., 179ff.
An informative website on ancient Egypt is the British Museum’s Ancient Egypt
Wikipedia of course has a vast amount of information on Ancient Egypt
