I've read that. It's aimed at "young adults" if I remember correctly, but it still makes for a good read.
Through corruption of the Dhamma comes corruption of the discipline, and from corruption of the discipline comes corruption of the Dhamma. This is the first future danger as yet unarisen that will arise in the future. You should recognize it and make an effort to prevent it. (AN 5.79)
"If you stand up and be counted, from time to time you may get yourself knocked down. But remember this: A man flattened by an opponent can get up again. A man flattened by conformity stays down for good." - Thomas J. Watson
I read it while it was still in print. An excellent book; geared mostly to younger readers as retro mentioned, but still good and informative.
Radhika Abeysekera is an excellent Dhamma book author. Her books are published and distributed for free through the Corporate Body . . . in Taiwan and when they go out of print, she has transferred her books to online sources so they can be distributed more easily and still for free with less costs.
