I definitely enjoyed Marcella Burnard's Enemy Games, if not quite as much as her Enemy Within. The action is every bit as heart-stopping. The plot is every bit as twisting and turning. The characters are every bit as dramatic. Unfortunately, although I could understand Jayleia and Damen having difficulty allowing themselves to feel for each other, I think it was carried on too long. It became very difficult to understand why they continued to feel that it would be such a terrible betrayal to indulge in their emotions at all. I will at least say that we are eventually given legitimate reason to help explain some of Jayleia's more frustrating actions, so if you can't understand why she's doing what she's doing, hang in there.
It was a little tough at first to match up Jayleia with her portrayal in the first book. Maybe I'm misremembering, or maybe it's just that she hid her personality that well, but it felt a bit jarring.
By the way, make sure you read these books in order! There's an extremely strong arc to the story, and despite the fact that the books largely follow different characters, you definitely need to know what came before.
I still love the world-building in this series. The politics are fascinating; the aliens are horrifying (we find out quite a bit more about the mysterious Chekydran); the characters' work studying infectious diseases is intriguing. There are, once again, some fairly dark moments in this book, so make sure you're up for that. There's also some delightful sexual material. As futuristic romances go, Enemy Games is very enjoyable and a good successor to Enemy Within.
