OK, so technically Hot Toy is a novella, Jennifer Crusie's contribution to the Santa, Baby anthology St. Martin's just released. But I've read a 700-pager or two this year, so I think I can count a novella as a book read. It balances out.
If you're cranky or stressed about Christmas, this is the book for you. The heroine goes out on Christmas Eve to buy the year's hot toy for her nephew and gets the last one in the store--only to discover that the banged-up, marked box meant that she got the copy with the spy codes hidden in it. Violence and mayhem ensue.
And as a writer, I've got to love a story where the last line of the first paragraph is "I need a Major MacGuffin." Deliciously meta.
