This short book is essentially an advertisement for Karen Maitland’s other works. She is known for medieval thrillers, a lot of which contain really evil children.
Wicked Children is made up of three parts: one explores some of the real-life cases of children abusing their power and committing acts of murder, which inspire her own characters. The information about these cases is interesting (provided you have at least some interest in evil children and murder) and really quite shocking. The stories of children getting people hung or burned at the stake for witchcraft by pretending to have been cursed or possessed are truly intriguing. But sadly, that’s about as good as Wicked Children gets.
The second section is also quite interesting – a brief list and description of some medieval poisons and cures. However, the final part is simply sample chapters from two of Maitland’s novel (hence, an advert).
What’s there is interesting, but it’s very short. I wouldn’t pay for it.
