Blackthorn Key

Christopher Rowe, apprentice to master apothecary Benedict Blackthorn, is learning all his master's secrets - like how to decipher complex codes and puzzles and how to transform simple ingredients into powerful medicines, potions, and weapons.

London, 1665. Fourteen-year-old Christopher Rowe is apprenticed to master apothecary Benedict Blackthorn. In Blackthorn's shop, Christopher learns the delicate secrets of transforming simple ingredients into powerful medicines, potions and weapons. His beloved master guides him with a firm, steady hand - instilling him with confidence and independence that prove increasingly vital as Christopher learns of a mysterious cult preying on the most learned men in London.

The Black Death has returned to London, spreading disease and fear through town. A mysterious prophet predicts the city's ultimate doom - until an unknown apothecary arrives with a cure that actually works. Christopher's Blackthorn shop is chosen to prepare the remedy. But when an assassin threatens the apothecary's life, Christopher and his faithful friend, Tom, are back to hunting down the truth, risking their lives to untangle the heart of a dark conspiracy.

Boils, blood and a burning fever - the black death has returned to London.... As the dreaded sickness spreads through the city, striking down rich and poor alike, an unknown man arrives with a miracle cure. But when an assassin threatens the life of the city's new saviour, young apothecary Christopher Rowe and his faithful friend Tom must risk their lives to untangle another dark conspiracy.

Wherever Christopher Rowe goes, adventure - and murder - follows. Even a chance to meet King Charles ends in a brush with an assassin. All that's recovered from the killer is a coded message with an ominous sign-off: more attempts are coming. So when Christopher's code-breaking discovers the attack's true target, he and his friends are ordered to Paris to investigate a centuries-old curse on the French throne. And when they learn an ancient treasure is promised to any assassin who succeeds, they realize the entire royal family is at stake - as well as their own lives.

Christopher Rowe has no idea who he is. After being shipwrecked in Devonshire, he wakes up alone, his memories gone. Villagers tell him he was possessed by an unseen evil, and only became conscious after being visited by the local witch. As Christopher tries to get his bearings, he realizes his current state may be far from coincidence. Dark events have been happening in this corner of Britain - village children are disappearing without a trace. There are whispers that the malevolent ghost of the White Lady has returned to steal the children away, one by one, and consume their souls.

Christopher, Tom, and Sally are back in London at last. Everyone is relieved at their return - the plague has ended, and the king, pleased with their service, offers a surprising reward. But trouble has followed them home.... First, an old friend is ambushed and left for dead. Then an anonymous letter arrives at Blackthorn - a mysterious warning hidden inside a riddle and secret code. As Christopher and his friends begin to investigate, they soon discover they’ve stumbled upon a plot to kill the king...and anyone else who dares stand in the traitors’ way.

The stakes are higher than ever when the Raven sets Christopher up for a horrible crime, leading him to be locked away in London’s most notorious prison. This terrible act is the first in a series of games the Raven plans to play with Christopher...games that are as dangerous as they are challenging. Once free from prison, Christopher, Tom, and Sally engage in a cat-and-mouse game with the Raven that takes them all over London. Can Christopher outwit the Raven one final time and finally unmask him? And what price might he have to pay to achieve that?
