Today's post will be short and sweet.  Please visit Goodreads.com - the online site for readers and authors to share their views and reviews on books they have read or intend to read.  For the next month (until Feb 18) I will be giving away signed copies of Radical Equations, the fourth book in the Bonnie Pinkwater mystery series.  For those of you who aren't familiar with Bonnie, she is a high school mathematics teacher in the small Colorao town of East Plains.  She uses mathematics and her knowledge of historic mathematicians to solve murders.  All you have to do is go to Goodreads, register to win, and the drawing will be on or around Feb 18.  No strings, no hassle.  That's it.
