YMMV / Tamsin

• Complete Monster: Judge Jeffreys is a brutal judge whose actions haunted the town of Dorset, England for centuries. Sent down to deal with the Monmouth Rebellion, Jeffreys executed hundreds of people, innocent or not, through brutal quartering and hanging their bodies on pikes and trees, even causing a little girl to die from stress during a brutal interrogation, while selling hundreds of others into slavery. Gaining a fascination with the young Tamsin, Jeffreys murdered her lover Edric and sexually harassed Tamsin, causing her to run out into the cold and catching pneumonia, and he made her believe that Edric stood her up, using her last words to send The Wild Hunt to chase Edric's soul for eternity. Released centuries later as a ghost, Jeffreys plans to infuse Tamsin's soul with him so he can keep her to himself forever, before attempting to sic The Wild Hunt on the teenage Jenny.
• Harsher in Hindsight: "For a moment my insides fell off the World Trade Center". The book was published in 1999. Events since may have made the line only more appropriate.
• What Do You Mean, It's Not for Kids?: While the book centers around a juvenile character and involves many magical creatures, the author intended it as a fantasy for adults. It even won the Mythopoetic Award for adult literature. That said, other than a few sidelong references to drugs and a very few curse words, there's nothing in the book that a mature tween couldn't handle.
