“My favorite author! Couldn’t wait to read this so I had it sent ahead of me to my vacation destination. I tried really hard, I really did, to slow myself down to savor this book – but alas, read it in a day and a half. It was another great Cal Donovan adventure. I highly recommend it.” Amazon Review
