OMG!!! What an emotional roller coaster. This book had everything - amazing and captivating characters, a great plot, danger, intrigue, great dialogue, heat, passion, lots of hot sizzling sex and zombies. I was hooked from the first page, there was no gradual build-up, the action stared from the first page and continued until the last page. This series is addictive, you must read the first two "Ghost Ops" novels- Heart of Danger and I Dream of Danger to really appreciate this book. I highly recommend anything written by Lisa Marie Rice. Picks up immediately following its predecessor, "I Dream of Danger" when Jon Ryan rescues Elle's friend Sophie Daniels, who has the formula for the vaccine that will Save The World.Jon and Sophie are nothing new in Rice's hero/heroine repertoire. She's a brilliant but socially awkward Damsel in Distress. He's a warrior and loner who's a stranger to emotions. They meet, have explosive sex, and fall in love....in about five minutes.Rice almost breaks new ground with a plot twist when Jon's infected and Sophie must use her hidden talent to intervene. But it's all over so fast that it loses its impact. And when the Haven folks start imagining the Utopia that will develop after the infection is cured it just seems incredibly naive and foolish.But, if you can get over some of the glaringly large plot holes and just enjoy the action, suspense, and hot sex, it's quite a fun book.
