No. There are no good books on nano reefs. It's not easy to write a good book about a bad idea.
There are a lot of other books about modern reefkeeping which can probably apply to nanos with a little adjustment. The Sprung/Delbeek series ( volume three comes out this month ) should be very good, and in Europe the series by Alf Nilsen & Sven Fossa is also very good.
www.nanoreef.com is a webforum & info site dedicated to nanos, and many people find it helpful.
