I've read that. It's aimed at "young adults" if I remember correctly, but it still makes for a good read.
If you have asked me of the origination of unease, then I shall explain it to you in accordance with my understanding: Whatever various forms of unease there are in the world, They originate founded in encumbering accumulation. (Pārāyanavagga)
Exalted in mind, just open and clearly aware, the recluse trained in the ways of the sages: One who is such, calmed and ever mindful, He has no sorrows! -- Udana IV, 7
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.
