Mysterious murders terrify Cambridge…

An ancient plague threatens London once more…

A coded manuscript holds the key, if it can be deciphered in time…

Historian Trina Piper is summoned to the British Library to authenticate a coded manuscript believed to be authored by Isaac Newton himself, while London cowers under the pall of a series of ghastly murders.

When a malicious Russian scholar appears and demands the manuscript, Trina realizes that Newton’s papers and the murders are connected, and both hint at something far more ominous: a secretive Order dedicated to reviving alchemy for sinister purposes.

Caught between occult mysteries and a shadowy cabal, Trina must find a way to save not only herself, but all of London. With the help of a handsome and resourceful Interpol agent, she rushes from Westminster’s fog-filled alleyways to the colleges of Cambridge University in a race to prevent a forgotten seventeenth-century plague from being unleashed… again.

As Big Ben ticks down, she discovers that Newton carried a secret so dark he buried it beneath layers of stone and forbidden sorcery. But now the secret is out and people are dying.

Can Trina solve the Newton cipher before it’s too late?
