Christopher Lee has produced an incredible biography on Fanon that at once covers Fanon's philosophy, personal-political context and the greater events occurring during and after Fanon's brief, yet powerful life. That said, there are also some underlying and quite troubling issues.
The strength of Lee's account is the sprawling historical trajectory that he places Fanon into. At one point, Lee remarks on Fanon's book 'The Wretched of the Earth' as being both a critique of the events unfolding and about to come to fruition in Algeria, but also as a critique of those who will inevitably declare a state of 'post' coloniality prematurely. Likewise, Lee outlines the (sometimes antagonistic) relationship between Fanon and the Algerian Liberation front (FLN).
In general, Lee's book acts as a good introduction to Fanon's philosophy, but there are some glaring errors that bring down the overall quality of the work. Lee, for example, suggests that 'Black Skin, White Masks' lacks "an overarching narrative structure." Its hard to imagine reading BSWM and not seeing the unified thesis of colonial subjects having to literally and figuratively mask themselves via the white gaze. There is a deeper series of movements in the text that can and should be unearthed, which I recommend turning to Lewis Gordon's work as a corrective.
A more troubling remark Lee makes follows immediately after the above where he writes, "it must be emphasized once more that Fanon was a French citizen, not a colonial subject as such."(76) On the one hand, Lee simply intends to suggest that Fanon had access to and enjoyed some assimilation or privilege in French social-political-cultural. However, that is precisely the COLONIAL problem Fanon is delineating in BSWM and his entire corpus and being. Fanon IS a colonized subject of French colonialism. That is literally his biography. This is something that Fanon cannot escape either physically by traveling to France (as well as fighting in defense of it) or Algeria, nor can he escape it culturally, linguistically, or historically etc. at least not in the sense of assimilation.
As a biography, Lee's text is good. As an explanation of Fanon's philosophy, it has some issues, but still relatively good. I would recommend reading Fanon's actual words if you are looking for a better and more robust understanding of Fanon's though.
