The Kingdom of Caux used to be a peaceful land where people studied plants for healing 
purposes. Now, Apothecaries have been outlawed, and the citizens of Caux have found a new pastime - poisoning. If you cannot afford a Guild Accredited Taster to screen your food, you 
must fear for your life. So how will the kingdom ever return to its former glory? Meet Ivy Manx, a brave girl with a gift for potions. Along with a wise crow, a bumbling young taster,  and the author of The Field Guide to the Poisons of Caux, she will take on evil King  Nightshade and unlock secrets from her past. At turns hilarious and harrowing, the gripping  first book in this epic trilogy will have you considering hiring a taster yourself. Ages 11 
and up.
