Why did I love this book?
I was fascinated with the heroine Isabella and enjoyed watching her grow throughout this series. In Book 1, The Tower's Alchemist, she is like most young women her age. She could be content to spend her time having fun with friends, reading brides' magazines, and planning a future with the man she loves. But the world is at war and the good guys need her for her unique and particular talents. She accepts what she thinks will be her last mission. It’s no small task; she aims to stop the Nazis from deploying a monstrously deadly bio-weapon. The secret service she works for and the bio-warfare were inspired by actual WWII events which made the story even more believable. By Book Three she has embraced her special powers without losing her humanity. I liked her persistence and dedication.
