Davidia and the Foreboding Dinner

Best friends Davidia and Slirander find themselves caught up in yet another adventure, this time in the fascinating land of Dododotovia.
Davidia is one of five guests invited to a lavish mysterious dinner with four other perfect strangers. Slirander feels it is too dangerous for Davidia on her own, so she travels incognito in the magical black pearl pendant which Davidia wears on her neck.
A five-course dinner of unusual taste sensations awaited; each course imbued with imaginative flavours and weird-named offerings, served by overly-attentive staff and five changes of clothes. But why? Did the free dinner come with a price? There was certainly an air of foreboding to this one. The guests didn't have an inkling?
The precocious, outspoken Davidia questions her hosts' every motive, much to their chagrin and those of the guests. Determined not to comply with the subserviency expected of the dinner guests, and warned by Slirander about the foods she should not consume, Davidia ventures outside the dining room to feign eating and falls down a shaft, disappearing into a tunnel of sludge and into the chocolate factory land of Dododotovia.
To assume obscurity and escape, she has to make the right twists and turns in the labyrinth of tunnels in this chocolaterie. She discovers that Dododotovia is the secret factory farm for the mysterious ingredients used in the exquisite brand of chocolates served to the dinner guests, the taste guinea pigs.
How did she escape being the target of a life of servitude to the Dododotovidians? And what of the other guests?
Another fascinating adventure in the Davidia series.
