I discovered Tamora Pierce as an adult who still likes to read YA coming-of-age stories. While not as complex as the more recently written books about Beka Cooper, the quartet of books about Daine, which starts with Wild Magic, still satisfies.
My reread was prompted by my younger son who after devouring the Erin Hunter Warriors series and the Kathryn LaskyGuardian's of Gahoole Juvenile Series, started to read Wild Magic. He was thrilled to have Mom reading the same book he was! So Wild Magic has the advantage of being appropriate for younger readers (he's a precocious 8/3rd Grade) and still interesting enough for adults.
