Yes. "Wings of Fire" is an excellent book; a must read. Also, if anyone's interested in knowing about ISRO's origins, their "hacker culture" etc. then I recommend these two excellent books: "A Brief History of Rocketry in ISRO" by PV Manoranjan Rao, P Radhakrishnan; and "India's Rise as a Space Power" by Prof UR Rao. These two books give an excellent overview on how ISRO was started (starting from INCOSPAR, TERLS, Sounding rockets, Rohini, Aryabhata, SLV, ASLV, PSLV, INSAT, to GSLV Mk3).
