This is the story of a secret - the secret to the best-tasting chocolate in all the world. But I warn you, the most delicious things are never good for you...

Members of the villainous Midnight Sun never eat - so why are its leaders hiding out on a chocolate plantation in Africa? Ms Mauvais is masquerading as a nun, running an orphanage, and Cass and Max-Ernest fear blood chocolate is involved.

While the Terces Society investigates in Africa, Cass and Max-Ernest learn what they can about the mythical Tuning Fork, and Cass starts to wonder...is famous chef and chocolatier, Senor Hugo, really who he says he is?

When her mother goes missing, she and Max-Ernest must survive the terrors of the jungle to stage a rescue mission in their most thrilling and taste-filled adventure yet!

If you're tempted, take a taste, but just remember...this book is not good for you.
