The Asters are a diverse group of teenagers, magically and culturally, whose adventures take them to all parts of the world, both above and below ground, filling a gap in the YA fantasy genre that I wanted to read but couldn’t find. These YA fantasy stories are full of magic and adventure, action and jeopardy, sacrifice and betrayal, deep bonds of friendship, and a light touch of romance. The Aster stories are a fantasy series written for young adults aged 13 and older. There are scenes depicting serious injuries which might not be suitable for some readers.
