Why hadn't I heard of Shelly Laurenston before? I loved Pack Challenge. Such a fun read. Awesome friends--we really don't see enough of that in romance--a heroine with a temper, a hero who likes his woman mean-tempered...that's my idea of romance heaven, right there. The world-building needed work and I sometimes felt I was being hit over the head with the fact that Sarah and her friends were such badasses, but all is forgiven. I spent most of this book with a grin on my face, a rare occurrence.
