Queen of Teen - winner

News I've missed by being away (part 1!). The winner of the Queen of Teen 2010 is Cathy Cassidy. From the Queen of Teen website:

She's the bestselling author of GingerSnaps, Angel Cake and Indigo Blue...

She's just launched her brand new series, Chocolate Girls...

She also writes the Daizy Star stories for younger readers...

Obviously the books are very popular where I work but I haven't read any Cathy Cassidy yet, so which book should I start with?
