About 15 years ago I read this really good book, but time and age have taken their toll and I can not remember the title or author.  It is a fantasy choose your own adventure about a girl who's father is kidnapped and she has to use his bag of magic stones to save him.  It is part of a four book series.  Another one in the series is about a girl who is kidnapped as a baby and raised by an evil warlord, another is about a druid who has to rescue her sister and the final one is about a girl who uses her brother's armor to become a knight and save her family.  If anyone can help me with these books,  I am desperate.

The last one vaguely reminds me of a book by the author Tamora Pierce, although I don't think it was Choose Your Own Adventure...

check out abebooks.com in their search they can usually come up with the title not sure if B&N has one or not doesn't hurt to check!

no idea but here is a list of Choose your own adventure books by year.
