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.
