A superbly written addition to this riveting series.

The three young protaganists venture outside of the customary confines of the apothecary shop and step into the very adult world of spies, treachery and political intrigue. This is the best of the three stories presented, with plenty more story to tell, and I eagerly await the next few offerings!

Best of all, the author does not indulge in the happy-ever-after syndrome which spoils so many books written for young adults.
