Two Hearts Under Fire ( Two Hearts Wounded Warrior Romance Book 8) by Tamara Ferguson.
I had read every single book in this series and they just keep getting better and better. This author continues to amaze me with every book of hers!!!! The way all of the characters just mesh so well together just simply amazes me. This book is filled with romance and suspense and will keep you wanting more.. this is definitely a MUST READ and I highly recommend not only this book but the entire series as well!!
