Great new book on Brian Eno is out. I bought a copy of "On Some Faraway Beach: The Life and Times of Brian Eno" today.
It is not all about U2 but as Eno's worked with U2 there is U2 content.
I just started reading it. Lots of interesting insight and funny Eno-esque stories about Brian. Definitely worth a read. Come on, he was in Roxy Music, pioneered ambient music, produced Bowie, Talking Heads, U2... What's not to like? Highly recommended.
You can get it cheaper than I did, at Amazon.
