Safely back in 1803 England, Merlin's Irregulars are more confident, proud, and powerful, but class distinctions complicate their relationships until the mages are called upon to rescue a vitally important French scientist and his family from Nazi-occupied France.

When Papa goes away for a little while, his family tries to cope with the separation by adopting four dogs and a cat.

"Simon Grenville has his own reasons for wanting to destroy Alex Reynell. The man used to be his best friend, until his practice of the dark arts almost killed Simon's sister. The beautiful half-naked stranger Simon meets in the woods may be the perfect instrument for his revenge. It will just take a little time to teach her the necessary etiquette and assemble a proper wardrobe. But as each day passes, Simon is less sure he wants Joan anywhere near Reynell. Because no spell in the world will save his future if she isn't in it."
