This was an excellently written story of a thought-provoking topic. As a Young Adult novel, the writing was not complex, but interesting enough that I read through very quickly. A story of a couple of elderly ladies, part of a group that is on the verge of death but are given a new drug that is supposed to allow them to 'un-age' to at time when they are younger and then an 'antidote' is given to stop the process. The ladies find life getting younger a challenge and therein lies the story. I won't give away the ending, but who hasn't wondered what it would be like to find some kind of fountain of youth? A great story for that progressive young reader in your life, and not bad for adults either!
