Sorcery and Cecelia by Patricia Wrede and Caroline Stevermer

 Cecelia is disappointed when her aunt won't let her have her first Season in Regency London with her cousin, Kate.  The two girls have been inseparable since childhood, so they vow to write faithfully while Kate is away.  The magical trouble starts when Kate is invited to see a family friend initiated into the Royal College of Wizards.  Kate has a curious encounter with a powerful witch and soon both Cecelia and Kate are swept up in a dangerous mystery that involves two young men, two evil wizards, and chocolate pot that is more than it seems.

I read this book years ago but I guess it was before I started keeping this blog.  I decided to read it again when Kelsey, my daughter-in-law loaned me another book by Wrede that reminded me of this one.  This one came about when Wrede and Stevermer decided to play a game where they wrote letters back and forth one summer which each person taking on the role of fictional character.  Both authors enjoyed the game, and decided that, with a little editing, the pretend story they made up through their letters would make a good book.  The writing and plot are not as good as some of Wrede's other books, but it is a fun story and a clean magical historical romance.  (2004, 336 p)
