The Probable Future tells the story of the Sparrow women - a family of women who all receive a "gift" on their 13th birthday. The first Sparrow woman, Rebecca, no longer feels pain. Some women can tell when someone is lying, some can run faster than a deer, some can walk through fire or stay under water for 20 minutes. The youngest Sparrow, Stella, can see death - she can look at most people, and tell how and when they will die.
I like Alice Hoffman because all of her books have an element of magic and an element of romance - it's not cheesy, in-your-face romance, it's subtle. She also wrote Practical Magic, which is an excellent book and a good movie (although the book is better, as is usually the case).
This book doesn't contain have much language or any sexual content, although most of her books do have some of one or the other, or both.
