Many thanks to Bob, who devised the winning title for the fourth book in the series! It was hard to make a decision because you folks were so creative and thoughtful in your suggestions. But since book 4 takes place partly in the diamond mines, and the old-fashioned word for cut diamonds was brilliants, it seemed to suit perfectly. As well, the invention that changes the course of Claire’s life is, in a word, brilliant. If she does say so herself.
And so is Bob. You win a copy of the book when it’s released in February 2013, Bob, in whatever format you choose. Thank you!
(And by the way, I’m keeping a list of these titles. Some practically beg for their own books.)
