"Ms. Koch kept the action and humor levels high in this book. It was one of those that the reader doesn't want to put down. I love this series and can't wait for the next installment." —Fresh Fiction
"Alien Diplomacy has everything I love about this series—the jokes, pop culture references, the hot aliens and a clever but still real heroine. I love how Koch gives her characters strength but never makes them seem untouchable. Kitty is definitely a gal I would love to call my friend." —Book Lovers Inc.
"Without a doubt this is one of my favourite series and one that I can't recommend highly enough." —Feeling Fictional
